Controling relays with contact closure

I use a 8 relay wireless relay control to operate 4 hydraulic valves and a 12 volt hydraulic pump. With the KFX I programed it to activate 2 relays simultaneously, for example, I activate relay 1 to open a valve and relay 5 to activate the pump, or relay 2 to activate another valve and again 5 for the pump. I would like to add a separate panel control for this system. I know I can use contact closures for each operation valve, Relays 1 though 4 but is there a way to activate relay five simultaneously like with the KFX programming? Using a separate contact closure for relay 5 is not ideal, the pump is not designed to be operated continuously, and holding down 2 buttons is not ideal either.
thanks for any advise.

Hi I assume you’re using the AD8 Relay Activator feature of the ProXR Lite boards for relay activation through the onboard ADCs. Unfortunately this feature does not have the capability to control multiple relays with the same granularity as the command set used by the KFX module.

Jacob, Thanks for your input. I expected your answer was the way this was. I think I can design a work around for the pump control. It would have been nice and clean if there had been a way to do it though the AD8.
