Single Staff Member - Multiple location availability?

I am trying to have a photography services and Studio on the one website.

I want my booking services to be in one place, so I want to be able to have bookings available for location sessions and studio available at the same time? how can I set myself up as extra staff so that if someone books a 5pm location session, the 5pm studio session is still available? or am a I better off getting seperate booking software for my studio bookings?
