Different services with specific weekday & time

Hello there,

I have 3 different lessons for which I need specific times in the bookings:
– Tabata only on Tuesdays at 18,
– Spinning on Wednesdays at 19, and
– Functional training on Thursdays at 18 (more to come).

I need to be able to select the lesson and only see the days on which the lesson really is. Now the days just show and disappear in an unspecified order. Can I set it somewhere & only have one calendar shown on the page?

Thanks in advance!
