The modeler provides helpers such as the Actor and Group selection field:
But these fields make is very difficult to reuse configuration across BPMNs or across different tasks.
Consider that a UT will have multiple actors and multiple groups applied to it. I then decide i need to copy values from UT1 into UT2. UT2 already has a series of configurations applied, so i cannot just delete UT 2 and copy the entire UT1. I need to be able to easily copy the values from UT1 and apply them into UT2.
