Top priority for us and a huge annoyance for the reps (and a time suck for the admins who should not have to spend time doing this). This is a basic feature in Calendly and it's a detriment to Chili Piper that you can't do it.

I want to create a booking link to display the available slots of two or more users at the same time. The available slots of more than two users should be presented via link, where the customer can freely choose the best fitting slot (no pre defined slots)
In our case, the agents who are part of a "group meeting" always vary, which is what makes it different to set up X "fixed" group meetings, as members always vary and the users also want to be able to customize the subject / email text for different book meetings at any time.

This is kind of the whole reason we signed up for Chili: The ability for team members to set up meetings on the fly with anyone else in the organization that is also in Chili. Right now, we have to create an inordinate amount of "Group" links to enable 1 person to include several different people in their meetings. What you currently have is not a sustainable solution for our organization.
