Eligible User Pools for AI Booking Rules

Your AI booking rules can now route to a particular group of reps instead just a calendar (all users in that calendar) or a single person within a calendar 
— so the soonest appointment is never blocked by one teammate's calendar.
When you set up booking rules for your AI agents, a rule can now hand the calendar a pool of eligible users rather than one specific person. For example:
"If the contact's zip code is 11706 or 11707, book with Joe or Tom in Calendar A — otherwise book with Sally or Bob in calendar B. Let the calendars distribute among eligible users."
How it works
The calendar keeps using its own user-selection strategy, just limited to the pool you specified:
Maximize Availability — the AI offers the combined availability of everyone in the pool and books the least-loaded rep who's actually free. If one person is on vacation or fully booked, the contact still gets the next real opening from someone else in the group.
Optimize Distribution — picks the least-recently-booked rep within the pool - not the intended use case for this feature (because optimize distribution balances out to the least recently booked rep, keeping availability to a single user), but it will still work.
Why you'd want it
This is particularly useful when you want to book among a particular group of team members, but don't want to select a specific one before booking (which limits availability for your customers to that particular team members availability).
No more calendar bloat. Instead of creating a separate calendar for every combination of reps, put your team on one calendar and let rules slice them into the right pool per contact (by zip, service type, etc.).
Easier to maintain. Change who handles what by editing a rule — no juggling dozens of calendars to keep track of.
Better availability + automatic balancing. Contacts get the soonest real opening across the whole eligible group, and bookings spread evenly among them.
Works with text and voice AI agents, and with the manual "Let AI Select Calendar" button (you can let it auto-assign within the pool, or pin a specific person).
If a rule ever points only to people who aren't assigned to the chosen calendar, we stop the booking and flag it so you can fix the setup — rather than quietly booking the wrong person.
