Reply to Saving midi mapping in reason?

not sure if this is in the right place but here goes.

just got an mpd off a mate and can having some problems
i can map the knobs and faders to reason using the ...edit remote override mapping... but my problem is that i want to change different synths live using the knobs on the combinators to change frequency and resonance and that kind of thing live. is it possible for me to assign the knobs on my mpd to four differnt knobs on a combinator , and then select another combinator and use the same mpd knobs to control another combinator? atm i have to change the mapping everytime i want to control a different synth which is useless live. and whats worse i dont know how save mapping either.

please help! i cant find the answers anywhere
