I was wondering if anybody knows of any AoE markers for this gloomhaven mod?

Anyone that's ever played a Warhammer 40k or old fantasy game on TTS will know they have rotate-able area of effect objects for flamethrowers and so on, which you can position over the top of your board and move around to hit the maximum number of targets. Like these: https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=462957889

I was thinking that would be a useful thing for Gloomhaven on TTS, but with hexes, as I'm starting to unlock abilities with huge and irregularly shaped AoE, and trying to mentally work out how to hit the most targets is often a little cumbersome.

If nobody knows any then I might try make some myself, but thought I'd ask first.
