How to allow multiple services with one provider at one time slot?

Hey guys, I bought appointments+, since the interface looked easiest for my client to work with. I understand now that this isn't a booking plugin, but I've already bought it, and so I need to make it work as much as I can.

I have one worker managing three unique for-hire type of rooms. Each room is available in two hour slots and he is only involved in guiding customers to the room they booked. As such, I only have one service provider, and three services; I need all three rooms available to be booked once at each timeslot. How can I go about this?

I've read many topics on the forums, but none have this specific problem and I'm not sure which approach would be appropriate. I would much prefer specific help rather than links to other topics.
