Akmor - thanks for the tip! I've gotten as far as making tokens for my monsters:
All those letters on the left are displayed from the area you normally drop your tiles.
Though for me to pull this off, I have to do some wonky things (as you'd expect, when you go off the beaten path a bit):
I found that I can't adjust the z-order of the tiles. Not usually an issue, because on any given layer, the tiles should all be on the same plane. But, that means my monster markers can end up underneath a tile, and I can't bring them to the front easily. What I did in the picture was create a layer for the monster markers, and when it comes time to snap my pictures, I'll set transparency to 100, and have my tile layer show the monster marker layer above it.
It doesn't look like I can make my own .wwz files like I can .tlx files, but I might try to extend the marker set to include all the monster markers. Not sure if I can have variable-sized markers there or what, but it shouldn't be hard to try it out.
Now to make .tlx files for my harbormaster tiles, and redo my plans...
