Is it possible or does anyone know if a power beyond circuit can be utilized on the auxiliary hydraulics of a Massey 5400 series tractor? 5455 with open center hydraulic system with 3 remotes and switch in cab to boost remote GPM. I am wanting to hook up a 2 spool valve with joystick cable control but still need the 3 remotes to be functional as well. Tractor has loader as well with cable controls to the loader valve. It is being fed from the tractor somewhere but loader also needs to be kept operational. Could I possibly tie into the loader circuit?

 Thanks for any input or suggestions.
