Heat pool & hot tub with 1 heater

Want to heat inground pool & spa with 1 raypack heater & Hayward variable speed pump.

Currently have pool & spa separated, each with their own heaters & pumps.

Is it possible with automation & valves to run both through the same heater on their own schedules?

thank you for any feedback
