Music Overlay - why can't you map the play/stop/record buttons?

While other controls can map via MIDI the play, stop, record, left, right, etc controls are all very useful for Ableton Live. So in the meantime Sensel isn’t really useful to me when I have portable controllers that do all this for me and more. I would like to see Ableton support in the future. And I am sure many more would too. It’s one of the world’s most used DAWs so if the Sensel team is focusing on making this a tool for music then support for it is a must.
