Yes you can share the body sprays with the shower head if you connect them to the top two outlets. The bottom outlet only runs alone so use it for the hand shower.
Normally the body sprays are on the outlet 3 and the shower head on outlet 2
You can find the piping layout in the instruction guide for the valve. Do not use body sprays that will use more than 3 gallons per minute total. If you do, they will drop off in performance when you turn the shower head.
