You can now define "Assignment labels" for each process and assign them to Execution Nodes. Adding, renaming, and deleting labels are done from the process header, while the Execution Node detail sheet is used only for assignment.
By selecting multiple nodes and right-clicking, you can add or remove Assignment labels in bulk. Assigned Assignment labels are also displayed on the Execution Node and in the "Assignment labels" column of the list view. Up to 10 Assignment labels can be registered per process.
