Limiting the number of workers scheduled in a particular time slot

Good afternoon:

We'd like to use Shifts as an approach schedule employee time. We're now limited in the number of people that can be in particular workspaces due to COVID-19 restrictions.

We'd like to allow employees to schedule their own space/time, but it would be helpful if we could cap the number of people that are occupying a room in a particular timeslot on the schedule.

Is there a setting that restricts scheduling once a cap is reached (in a particular time window)?

Thank you.
