Storing and Finding Files in “The Cloud”

Trying to find a good way to organize my data on the Cloud in a master, hierarchical directory/folder structure.

Let’s say for example that I have storage on iCloud, Google Drive, Dropbox, Box and Adobe Cloud (among other locations), with different categories of data on each.

Ideally, I want ONE master hierarchical directory structure, in which each base-level folder (e.g. Daughter One) will contain links to EVERY file related to my oldest daughter, including photos (which might be physically stored on Google Drive), Internet Favorites (Chrome web), Speadsheets (e.g. iCloud), PDF files (Adobe Cloud), Word files (Microsoft Office cloud), etcetera.

I do NOT want to re-create the master hierarchy on EACH Cloud service and then be required to update that hierarchy in ten different places every time I add a directory. I want the master hierarchy in ONE place, such that if I create, delete, move, promote or demote a sub-directory, I only need to do it ONCE, in one place. I am doing basically that now, and I ALWAYS forget to revise the structure in every location, meaning that a given piece of data is located in different parts of the hierarchy on each service.

I know I can create a master hierarchy structure locally (on my desktop PC for example). Hell, I do it now, with my home network. The master structure located on one of the computers on my home network, with different types of data scattered around the house. I could easily add links to the various Cloud locations, but I WANT the master structure to be located on the Cloud, so I can access it from any device or location.

Is there a way to link (a shortcut?) a location on one service to a directory (folder) or file on another service? This would let me create the master folder hierarchy on (for example) BOX, and then use Box to link all my data scattered across the Cloud.

For example, let’s say that I have a Family photo folder on Google Photos and a family calendars folder on iCloud. (Please do not get bogged in the nature of the individual files. I am simplifying). Is there a way to place somewhere in the Cloud a link/shortcut to each of those locations, within the same directory.

Putting the matter another way, say that I have photos on my Google Photos cloud drive, all my Numbers spreadsheet files on iCloud, and all my PDF files on my Adobe Cloud drive. Is there a Cloud-based location/service/app/software product that would allow me to create folder to all “family” data (with links to folders on Google drive, iCloud, Adobe Cloud, Box, etc), plus other folder for other categories each containing links to the various Cloud providers?

Related question.

Do any of the Cloud services allow you to put a file in one location (for example a photo of Daughter Eating at the Lake), and shortcut/link that file from various other locations (e.g. the Daughter folder, the Eating folder and the Lake folder)?

Yes, I know that I can (sort of) accomplish something similar with Favorites and/ or atags in some programs/platforms, but THAT does not let me use one, unified directory/folder hierarchy across ALL data types (e.g. photos, spreadsheets, Notes, word processing files, etc.)
