At the moment when creating a new meeting type, in the "location & calendar" section, one define a booking destination by 1. selecting a calendar account and 2. selecting a specific calendar.

This is clearly define and represent the calendar where the bookings are going to be recorded

In this section I think this would be a great addition to have an "3. select calendar(s) to check for conflict" step.

• This could/should/ list all the calendars available withing the selected calendar account, with a checkbox next to each.
• By default the specific calendar selected in step 2. would be automatically checked.
• yet doing this would make it possible to check additional calendar within the same account, for present availability and avoid double bookings.

Rational:
as an example, my availability is regularly split in between multiple calendars: 1 personal calendar, 1 group/team calendar etc..

being able to check for conflict with both calendar before making a booking effective in my personal calendar would be a great addition.

I hope this makes sense - thanks for considering,
