Can a therapist leave Grow therapy and then come back later?

Has anyone every left Grow therapy and then returned later?

I have a nearly full case load and I will make 20-30 dollars more for most clients if I move them to Headway/Alma. I plan on leaving Grow entirely and taking these clients which I believe I can do, but if shit hits the fan and I struggle with referrals I would love it if I could rejoin. Has anyone done this?
