Unable to export an .idx file from a simplified representation

In the ECAD/MCAD data exchange context it would seem that exporting .idx from a simplified rep would not make sense. The purpose of the .idx in this context captures and tracks the proposed design changes initiated by the mechanical and electrical users in Creo ECAD-MCAD Collaboration. It communicates design changes between ECAD and MCAD. If you are generating the state from a simplified rep that could result in errors depending on what is active in the simplified rep. You could literally be unintentionally corrupting the data exchange of the design intent if this was supported.

If you have a use case that is not covered by the above comments, please document it in detail if you are asking for an enhancement.
