Group Self Registration or Reservation Limits

Hello, would it be possible to set a max number of slots for group self registration or reservation.

An example would be we set the self reservation limit to 5. So, groups who have 5 or less people could create their own reservation and be automatically sent the information. Groups larger than 5 though would get a message saying thank you for your group request someone will be in contact with you soon to make arrangements.

Another option would also be within event settings allowing and limiting self reservation or registration by event. So, if we want to open our Tuesday nights to group self reservation but not our weekday morning events. Self reservation would only let those group leaders sign up for specific events that have group self reservation turned on.
