Import BCF in Model Coordination (and not only in Docs)

[ClaudiaHinrichs]

It would be very useful if the BCF import function will be available again in Model Coordination (as in the BETA version)

Reasons:

1. Collisions often involve at least two different models, so importing only to one model is not practical
2. Often, you don't want to communicate all clashes in a project as individual clashes (as BCF), but rather want to create grouped clashes in which are involved different models and communicate them as BCF
