Every problem begs for a solution. This question is probably a no-brainer for you veterans so here goes.

One time while editing, I clicked something and managed to get two flags to be active on a single combo (the first was on the top half of the tile and the second flag showed up on the bottom half. I didn't need it there so I fixed it, but now I've run into a situation where two flags are necessary, specifically Flag 4 and 6 on two different combos (burn trigger and bomb trigger respectively) each combined with 94 (Trigger -> Self Only). So... how do I do it? I've tried multiple combinations (shift-click, ctrl-click, alt-click) with no luck.
