Option to not pack anything listed in any/all VPK files

[granis48]

The option to exclude specific VPKs from packing is very useful for not wasting space in your map's filesize, but in games like gmod or momentum mod that mounts VPKs from many other games as well as its own it can get very tedious to manually select each VPK from every game.

Having an option to ignore files listed in any mounted VPK would be much easier and probably more intuitive than needing to select the ones you want excluded.

This could be a new parameter in the PACK step or even replace the current "Exclude VPK Files" parameter.
