Can OmniGraffle...

[Jonathan Sanderson]

A query:

Does OG have any concept of objects 'containing' other objects? That  
is, could I get a script triggered upon dropping one element 'into'  
another?

I want to build a workflow where a group of boxes can each contain,  
say, up to three blue objects but only one red object. Attempts to add  
too many objects to the container would trigger a scripted warning.

My impression is that this would be hard in OG, but I'd love to be  
wrong about that.
