Revealing masked area on hex map

[rhollander10]

I'm running a game that uses a hex map for party exploration. I'd like to mask the whole map other than their starting hex, and then reveal each hex as they explore it. I know how to apply a mask to the whole map, but I only know how to reveal a hex by drawing reveal rectangles on it, which doesn't look great. Is there a way to draw a hex using the reveal tool, or some other way to accomplish my goal?

Thanks!

try holding each of ctrl, shift and alt down when you use the mask.

Would be useful if FG could mask/unmask one grid box/hex at a time, or let us draw (un)mask grid-boxes/hexes. Would also be nice to get different pre-defined (un)mask shapes similar to pointers (especially circle).
