Blocking Out Other Classes When One Is Booked

Hi there,

I am looking for some guidance with the scheduling feature.
I have a photography studio and have set my calendar up as classes.
Everytime someone books in a session I have to go in and delete all of the other classes that clash with the clients selected session.
Is there a way to automate that the other times that clash with a selected time become automatically blocked out/un-bookable?
I tried the resources option but that didn't seem to work

Any advice on how to do the above would be greatly appreciated

Use appointments instead of classes. 

We initially tried this but people were booking at random times which made it hard to allocate other time to people - for us we would prefer to allocate specific slots - Using appointments doesnt really work, nor answer the question of blocking time out.
