Is it possible to perform a VCM session based only on items attached to a revision label?
It is possible to perform a VCM session based only on items attached to a revision label via the VCM Wizard: Include items page.
The Revision Label compares items with the selected revision label only. When checked, the drop-down box is enabled and displays the available revision labels. You can also specify which types of items in the view to include in the compare/merge.
This step only appears if you start the View Compare/Merge Wizard from the View menu.
