[FEATURE REQUEST] Channel permission mass-select.

Sometimes, I want to make a category enabling only mods and admins to type in, and when I have a lot of roles, it can be very tiring to manually select individual roles for each and every role. So, I propose mass-select/deselect. You would have 3 buttons. 1 above the "Do not allow", 1 above "Neutral", and 1 above "Allow". (But the symbol counterparts, not the actual words). You could then for example, select all permission as "Do not allow", then allow 1 or 2 permissions.
