Howto work with Baselines in Version Control

[grossh]

Hello,
we have several business domains within our model, each managed in its own package. Each business domain is handled by an own business analyst. The packages are under Version Control, but each with its own intervall for check-in.
If all fits together a release is prepared, marking all this current checked in exports with a baseline (revision) within the version control.
For the next release some (or all) of the packages might be amended and checked in again with different intervalls.
The development team needs all the packages for this release.
What I would like to do is to perform an "Get latest for revision/baseline", so a developer does not need to get each package manually by using
Package Control -> File History -> select specific version -> Retrieve
and hopefully uses the correct version all the time.

Any sugestions?
Thanks in advance.
