Ana macro mapping in live 9

Im trying to figure out how to stop the ana settings defaulting to zero when I map them to macros in ableton live 9. its very frustrating. i.e mapping the reverb dry/wet to a macro in ableton makes it go to zero. I know the long way round is to go into midi mapping and set the low and high values there, but that can get very time consuming. Is there anyway I can make live not keep returning the values to zero automatically?

no… the way you suggest… going in to the mapping panel is how its done
