Would like to see options at the administration level for only allowing groups the ability to request facilities during a specific time period

We are trying to create a system that would make facility usage equitable among non-school-related groups. Facility use requests by outside groups are at an all-time high, and with limited spaces available, we are having a hard time making usage fair among all groups. This could be accomplished if there was a way to allocate day and time allowances for groups to submit requests.

But would also need the ability only to have this set during the school year.
