Foster Fitting/ Fill Probe

So I have an FX Bobcat and an EdGun Matador. My bobcat has a male foster fitting for filling and my matador has a fill port. I have a 4500 p.s.i.Omega tank that I fill both guns with. I usually unscrew the female foster (used to fill my bobcat) and attach the fill probe (used to fill my matador), but this is a pain. Does anyone make a fitting that is male foster on one end and female threads on the other that I can screw my fill probe into? That way I can leave the female foster attached to my hose for filling my bobcat and just "plug in" my fill probe for filling my matador.
