Nested segment two-way inheritance

Description - I thought I was being smart when I set up segments to contain learning assets for each product, then collected those inside segments for the business units that "own" the product, and then nested the BU version into larger org structures. I figured that this way, I could update, say, the product segment and that would populate to the BU and larger org segments. Or that if I updated a smaller segment inside one of the larger ones, the update would cascade down to the product segment.

The result has been that if a new asset was created, the changes are only applied to whatever I directly edit. I have to go add the new item everywhere that the related segments are nested into other segments. It is frustrating and time consuming and ultimately can lead to errors where not everything was properly updated.

I can see why it might not be desirable for this to be automatic for some use cases, but a toggle to turn on change inheritance would be great.

Why is this feature important to you - It would automate manually intensive labor to avoid errors and free up time to focus on bigger work.

How would you like the feature to work - Say that I create 26 segments, each for files starting with a letter of the alphabet. Then I create a nested segment including segments a-c, d-f, etc. And then finally, I used the nested segments (a-c, etc.) to  create a larger nested segment containing all of the alphabet segments.

Then I get 3 new assets, each a different letter of the alphabet. When adding these, I want to make the change once for each. Whether that's in the exact letter segment (a, b, etc), in the nested segments a-c, d-f, etc, or in the larger nested segment of all of the alphabet, I want that change to be automatically applied to all of these in the right places so I don't have to do it individually for each of the 3 new assets.
