Wish: 'All' and 'None' button in Match Properties popup

As the title says. Mockup:

Alternatively (or better maybe), it should be possible to ‘paint’ over all the checkboxes (mouse remains down), so they become selected/deselected.

Paint would be good, the other two can be done by right-clicking the checkbox (checked for None-clicked one, unchecked for All)

Duh… missed that! Thanks!!
