Again, it's only a few lines of PB code, (basically StartDrawing()/DrawImage()/StopDrawing()), so you can do your own procedure for that. We usually add new function when it's:
1) too complicated to do in PB (like AES, ZIP etc. It's fully doable using regular PB commands, but it's complex topic and needs quite some code)
2) not possible using combination of current PB commands
So yes, you have do some code here and here, and no, we won't do a CreateDoom() command
