Add select 'Sim' menu to tattoo overlay box
I would like to add an option for morague's tattoo overlay object here:
http://modthesims.info/d/239851 to first select a Sim on the lot (other playables, townies, NPC's) who should get a tattoo rather then only giving it to the selected Sim.
(Of course, I could just make those Sims selectable with Insimenator, Sim Blender etc. and then do it, but I'd really like to pass that step...)
Trying to read through the existing tutorials, but completely confused even where to start...
