Pixelmapping Compound Fixtures

Okay, compound fixtures work great! Thanks for that!
Now i'm facing the problem when patching Robe Robin 300 LED in Mode 1, i want to pixelmap these fixtures. In mode 1 Robe Robin 300 has 3 parts of LED's. The Outer ring, the middle ring and the center LED. So: #101.2 > #112.4 Record Plot 1. When placing the fixture-parts on top of each other it won't show all three the fixtures in the mapping visualisation.
Maybe there could be a solution for this by gigving the user a option to change the shape of the fixture in the plot...

When recording a plot like: #101 > #112 Record Plot 2 I'll get a plot which contains the Robe 300 Motion part and the Robe 300 Beam part. This is strange i think because there's nothing to pixelmap on attribute's like Pan Tilt or Zoom, or not?
