Is there a way to get the PDE CVS Map functionality with SCM

So in PDE, you can use the Map capability to get the version to append to a built plugin name from a tag in CVS, instead of using the current date, or the version out of the manifest. This is nice because if you are comparing to binary builds, you can see which plugins changed between the builds because many may have been built from identical source, instead of seeing every plugin as different(in the date case) or having to remember to increment the version(in the manifest case).

Is there a way to get something like the current baseline for a Jazz SCM component during a build, in order to add the baseline id to the plugin? I've looked at the ant variables that are available through the build and none of them are right for this granularity. The buildLabel property is useful for labelling the entire output, but not its constituent parts. Better than the baseline would be a state version for each plugin.

Any advice is appreciated.
