In Windchill SIM it's currently possible to add a structure of parts and dynamic documents to a baseline. But this can only be used as a reference. You can add the baseline to a workspace and work on the "creation" side, but you can't do anything on the "deliver" side (afaik).
The request is twofold:
To create a translation package from a baseline.
To publish a representation from a baseline.
Both seem a small step from the current capabilities since they work with a very similar package and collection rules as a baseline does.
Why? Because existing products are sold in new countries. This is accompanied by translation requirements to the specific languages. But if any of the child objects has been reused and revised in another top level document, it is now impossible to have the existing document translated. You can only request a translation as of latest. Also publishing a representation is ony possible as of latest.
