Devo F7 wiring cc2500 4in1 RF module

Hi Guys, I have disassembled the F7 transmitter to replace the RF module with the 4in1 module that slots in perfectly. My goal is to use the DEVO F7 with 2018-GT90 Frsky receiver. I have found limited info on people achieving the swap and need some help.

Is it possible to achieve a 4in1 on the F7?

Has anyone had success?

Does anyone know where the cc2500 pin terminates to on the controller main board?
