Appointments plus blanking out certain times on calendar

Do you have any video tutorials on this plugin, i need to block out 2 lots of time in one calendar, 12-1pm and 3-4pm I had set up another service provider but then the slots only show on that calendar as 3-4pm and on the main one as 12-1pm can there be a way to have both periods in the one calendar

Thanks

Tara
