how to to prevent the same user (or email address) from booking more than one scheduled call on my calendar at a time.

Hi team,

I want to prevent the same user (or email address) from booking more than one scheduled call on my calendar at a time. Currently, some clients are booking multiple duplicate slots, which locks up my availability for others.

Is there a native setting or a specific workflow within Calendly to restrict duplicate bookings per email address? If not, what is the best recommended workaround to handle this automatically without manually canceling events?

Thank you!
