It may make sense to allow multiple checklists to be attached to the same activity in the future.
One use-case e.g. could be that the subcontractor has an internal checklist which he wants to answer as well when working on the activity while he also needs to fill the main contractors checklist. Only the second one would need to be filled by the MC.
