Favorite as link to Folder

Right now Favorite just shows a containing Folder images. what if you have a folder and subfolders of the same photo session ?
I use session mainly to have the xmp files out and not a big catalog system i cant transfer\control well, i have many folders and many external drives i use.

I would love to see an optoin to direct to a folder location on the filesystem inside CO (hance Shortcut) or favorite will have a dropdown of the subfolders if there are inside.
