Scheduler One to Many for more than 200

[Siafu7]

Apologies if this is answered somewhere and my searches didn't bubble it up.  I'm trying to use scheduler to allow contacts to choose between multiple time slots.  However, one to many appears to cap at 200 maximum attendees despite this being a hybrid in-person (500 can attend) and Zoom (we have large meetings with 1000 attendees).  Has anyone figured a way around this?  Thanks!
