AutoCAD Inventor :: 2012 - Parts Derived From Assembly Lose Color

Concerning Inventor 2012...

We do a good bit of deriving parts from assemblies. We have a workflow that works well for us, we create PARTS, put them in an ASSEMBLY, then create new PARTS DERIVED from ASSEMBLY. We use Boolean to add/subtract and disregard parts as needed to create these parts. These parts are now given color and reassembled in an yet another final ASSEMBLY as needed and put into a drawing.

Through Inventor 2011 this worked well. 

In Inventor 2012 the color is disapering as soon as any change is made on a source part.

1 Changing the color does not work.

2 In the derived from Assembly, opening up (in the browser) the individual .ipt's and right clicking and clicking properties and changing the color only stays until the next change to the source prt.

3 Changing EACH individual face by right click, properties and setting the FACE PROPERTIES from "as feature" to "as part" does work, but is ridiculous to change hundreds of faces on each part. (especially considering we did NOT need this step in 2011)

Is there a switch in the registry (to turn off the standard “as feature” to the parts face).
