How can I offer multiple bookings as a same time? 

Hi @LucasCHP! What a great question! 

While Calendly does not have a recurring event feature at this time, many users encourage invitees to book their next meeting after confirming an event. I apologize for the inconvenience with this.

Standard, Teams, and Enterprise users can also take advantage of our invitee redirect feature! Rather than seeing the Calendly confirmation page after booking, invitees will be automatically forwarded to the website of your choosing. Check out this help center article to get you started.

The other workaround I have would be for once the invitee books the event within Calendly, either you or the invitee can edit the event on your calendar and set it up to repeat as needed. While this won't create an event within Calendly, Calendly will be able to check it for conflicts, so you will not be booked at that time.

I hope this helps, but let me know if you have any additional questions about this!
