Can I determine my daily meeting capacity?

Yes, you can. Because not only your working time limits your capacity. Every meeting within the working time also takes up your capacity.
With Scedule you can define per weekday what percentage of the day you want to spend in meetings.

If on Mondays, for example, you want to concentrate on the preparation of the week, then simply set the capacity in Scedule to 50%. You will be surprised how unstressed a working day with Scedule can be!
