Controlling lights from 2 bridges at once?

Heya, am fiddling around with this app and I’m currently running:
2 hue bridges, 4 rooms (2 on each bridge) and 17 lights split between them (went with 2 bridges to be able to do 2 entertainment areas at once as they were capped at 10 lamps)
Is there any way to create a group/zone or something so that I can control every light simultaneously? Would love to be able to just set a color or scene for the entire apartment at once without having to do it once per bridge.
