Need the ability for multiple customers to self-sign up for a single event

I am currently using the calendly app to allow employees to sign up for group meetings with various managers(staff in booking).  I would like to stop using this paid app and use something that is already integrated in my outlook calendar.

I need the bookings app to have the functionality for up to 6 employees (customers) to self-sign up for pre-set event times, given only a common link - not an individual invite.

Is this in the works?

With this in place, I believe the bookings app can then send reminders, allow customers to cancel or reschedule, allow managers/staff to cancel or reschedule.
