Mixing IO PWM OUT and FMU PWM OUT

Hi all,

I have PX4 and PM07 combo and plan to use it for quad. I want to connect ESCs to a nice 3-row pin-header on PM07, rather than solder cables to M outputs. Are IO PWM and FMU PWM ports interchangeable on PM07?

My idea is to connect PX4 (IO PWM OUT) -> PM07 (FMU PWM IN) -> PM07 (FMU PWM OUT) -> ESCs.
