Problem: My music download folder has gotten very large; it currently contains 550+ sub-folders, one for each album. When I need to navigate into one of these sub-folders (from File Explorer or an Open/Save dialog window), unless it starts with an "A," I have to do "too much" scrolling.

Desired Solution: Without having to move around the sub-folders, when I navigate into the music download folder, I'd like to see only 27 "sub-folders:" A-Z and #. So, clicking on "D" would display all my real sub-folders starting with "D," etc. Is this possible to setup?

Note that I am aware of Group By but that is not what I'm looking for; it would be really nice just to have those 27 "sub-folders" which contain the filtered list of real sub-folders starting with the respective letter/digits.
