Many times, releases have both DVD and CD releases (or even some that have more than one CD). There should be an easy way to select/deselect a whole group. The checkbox is there already (where it usually places the CD name, like "Live at abc" or "Demos and rarities"), but it's never filled out and it doesn't work, even if we select it first and then deselect it.
Hopefully this is an easy addition.
Thanks for the hard work into this great plugin
