I agree that we need this. I am looking to set up a mini-webinar so that people can join twice a day, but I want to restrict the amount of people so it is a small group setting.
Calendly does it so you can select the amount of people that you allow to join. So I could have a time slot where I allow 3 people to join. Considering moving over to that for this function, but wondering if it is in the works here.
