Is it possible to have a service provider with mutiple breaks in one day

I like to book my appointments in 12 min intervals so there are only 5 and hour. I know i can only go by the 10 minute intervals that the plugin allows. I figured the way around it was to have each service provider have a 10 minute break during each hour. Is it possible to schedule multiple breaks in a day or do I have to block out the time manually like I have been doing?
