When moving subepic out of the parent epic, there is no information it was moved in the former parent epic

When moving subepic out of the parent epic, there is no information it was moved in the former parent epic. There is an annotation when issue is moved out of the epic, but not for subepic. This lately was really confusing for me (when someone by mistake moved the subepic out of the parent epic).
