Hey @Tricia10607! The answer here is both yes, and no!
You cannot share via a single link all of the individual event types your three users have. Example: if users A, B and C all have one-on-one event types for showings under their own profiles, those cannot all be shared at once.
What you can do on our paid plans is create a Teams Page. On that teams page, you can create the events for all three hosts (users) and then share the single booking link (for the teams page) so that interested parties (invitees) can select the one they want.
Read more here about how to create “one-on-one” event types on a teams page (hint: you can’t, but you can use a Collective Event Type or a Round Robin Event Type as a one-on-one event type by only assigning one host).
I hope this helps!
