Currently I can define a share to my top level NAS/Win/Apple device, under which I have a myriad of shares (a lot are not media related)
I suggest defining a Label (which you currently do), such as TV which has a SMB connection to 192.168.1.60/Data/Video/TV (its not sharing the top-level DATA share, but instead goes into deeper folder. The same would apply for a label such as Movies which may be a AFP connection to 192.168.1.70/Media/Movies.
This means I do not need to navigate through lots of folder to find what I need (unless I define a Share at a much higher level)
Highlight the directory you want to create a shorcut to and then press and hold the Select button. A menu will pop up which has the option “Add to Favorites” … select this option and you will now find that the favorite will now appear directly under the top level Media menu; no more navigating though lots of folders to get to your favorite folder!
