Specific decal picker

Basically what I want is a tool like the paint tool, except you can pick specific decals instead of just a general category which randomizes the outcome on spraying. For example: You need a blood decal that looks like a wall splatter. Instead of having to spray and erase the decals over and over in hope that it’ll come up, you just select it. Would be real convenient for poses, and it doesn’t seem like it would be too terribly hard to code.

Hey, this bloke asked me to bump this for him without making him seem like an complete ass, so I’ll just make some half-arsed comment like “Hey yeah, this is a good idea. I often need one of these too!”
