Snowray enables merging the content of one Value Set into another. Clauses from the Inclusions and Exclusions sections of the selected Value Set will be added to the corresponding sections of the target Value Set.
For now, only three Value Sets can be merged into another one at a time.
Merging can be accessed from in editing mode only. The merge process can be started by pressing the action menu item called Merge value sets, which will open a new window where the Value Sets to merge clauses from can be specified.
No new Value Set will be created, but clauses from the selected Value Sets will be added to the Value Set that is being edited.
