I note in the class action output slots there are several custom slots in the skills output section. I am struggling to find out what these bind to or how to bind them to a specific roll. In my case I was hoping they could be bound to specific weapon rolls rather than just all melee attacks as the character in question his greater weapon master and re-rolls 1s&2s on damage rolls which are obviously different dice depending on the weapon used. Might not be possible but thought I's ask.
