MIDI Mapper: Record 2 CC Lanes at Once?

[Jasipi]

Hi. I've only just found out about MIDI CC Mapper but there's something i can't figure out how to change if at all possible.

Some of my sample libraries use CC11 for xfade and CC1 for vibrato.

Basically i want to make reaper think my keyboard CC1 control is actually CC11 and record into CC11 lane (recording xfade), and CC1 lane in reaper is still CC1 (controlling vibrato).

A little confusing but if you know what i mean cheers.
