At the moment, if users Bulk Edit an issue to be an Epic, the Epic Name will be blank but in Plan Mode, it will appear as unlabelled-<issue key>. If you edit the issue after bulk editing, you will be required to enter a new Epic Name for it.

For example, if the issue is TEST-1 and TEST-2, bulk editing these issues to an Epic will cause the Plan Mode to show the Epic Name as unlabelled-TEST-1 and unlabbelled-TEST-2.

It would be better if the Epic Name could be automatically populated with the Summary, instead of just unlabelled- as it will be more relevant. This way, users might not have to rename all the Epics individually.
