How to replace component baselines in a repository workspace from a snapshot with Eclipse

In a repo-workspace "A" containing multiple components, each components has a selected a baseline. Suppose another stream "B" has created a snapshot "S3" (delivered by a repo-ws to the stream) containing new baselines for those (and more) components. Now workspace "A" needs to use the baselines from snapshot "S3".

How to select snapshot "S3" in workspace "A" to replace the baseline of all corresponding components in a single go?

Alternatively, you can replace the baseline for each component in the workspace individually, but with many components that is a lot of work.
