Multi-map keys in grid recording mode

Hey,
I’m hoping this is just another dumb oversight of mine but was looking to use grid recording mode to automate the different sounds used in multi-map mode. This can be done to great effect in live recording mode but when I try to do it in grid recording mode only get the track sound. Bit annoying as it would be a nice way to be able to programme in the drums without having to scroll through the sound bank each time. Hopefully this is doable,
Cheers,
Paul
