AutoCAD Inventor :: How To Control Number Of Side Actions When Designing Multi Impression Tools

I have a question for all the mold designers out there! How do you control the number of side actions when designing multi impression tools?

I recently completed a job for a customer where the requirement was to have a 2 impression tool with one side action to control both of the impressions. I found that if you pattern a part within the mold design environment and then apply a side action, the side actions would be copied to each of the patterned parts. I have created a test part to try and illustrate this (which is way out of size and proportion!):- Even if I combine the inserts, I still get the same effect.
