Independent "Conflict Check" calendars per Booking Type or remove "set as primary calendar" limitation

Currently, TidyCal uses a global "one-size-fits-all" approach for conflict checking. If you have multiple booking types that represent different staff members or rooms, you cannot isolate their availability.

​The Problem: If I connect a secondary calendar for a collaborator (e.g., Pilates Instructor), TidyCal checks for conflicts across all calendars for every booking type. This makes parallel bookings (e.g., Physiotherapy and Pilates happening at the same time) impossible unless we disable "Avoid Conflicts" entirely, which then ignores manual events and leads to overbooking.

​Proposed Solution:

Allow users to select specific "Check for conflicts" calendars per Booking Type.

  • ​Booking Type A should only check Calendar X for conflicts.
  • ​Booking Type B should only check Calendar Y for conflicts.

​This would allow small businesses to manage multiple staff members or resources under a single TidyCal account without their schedules blocking each other.

Additional Note / Alternative Solution:
​"Decouple availability from the Primary Calendar"
​"Instead of having all Booking Types depend on one Primary Calendar for conflict checking, allow us to assign a different 'Main' calendar to each Booking Type.
​The current 'Primary' structure creates a bottleneck for teams. If we could treat each connected calendar as an independent entity, we could manage multiple staff members without their schedules interfering with the main account's primary events."
