Can an adorer request a substitute for multiple dates at once?
At the moment, no, adorers cannot request multiple substitutes in a single action.
If you have an adorer who will be gone for an extended period, here are some options:
The adorer can request a substitute for each date individually.
Admins and captains can assign each date to other adorers.
The adorer can set an end date on their current commitment and create a new commitment starting on the day they will return. Another adorer can create a commitment to fill in the gap, starting on the day the first adorer leaves, and setting the end date to just before the first adorer returns.
