Categorize Sounds / Music / SSF / Callouts / Rom, etc so they can be adjusted globally or per table

It would be awesome if VPE's sounds can be categorized and adjusted for volume separately. For example being able to assign a sound to the following categories:

Music, Sounds, Callouts, Mechanical / SSF, ROM, etc

...and then being able to adjust the volume globally (and per table) for each one, like we can currently for Sounds and Music... instead of just playfield and backbox categories like we do now with VPX.

Of course it would be ideal if we could have the option to select an item in the editor and assign a sound, and then categorize it for SSF... which then VPE would automatically know its position and output it for SSF in the correct channels / sound device. The ideal being no code needed for SSF.
