Has anyone else noticed?

With the rollout of traktor pro 4 and all of it amazing new features. There is one feature i desperately want/need.

When mapping midi controller i assumed that i would be able to mapp controls from stem decks. Like the volume kill, volume control, filter kills, filter controls. Fx send kill, and fx send controls.

But these features are not available when i look in the mapping editor.

We do however have controls for the pattern player.

Does anyone know if these will be added soon, or why they were not added to begin with? Are we possibly getting a dedicated controller for that specifically?
