Force a track to be monophonic?

In the new OS - which is really, really cool!! - Can you force a track to be monophonic somehow? The polyphony is defined on a kit level and it kind of tells you “ok you can have voices so and so to be allowed to play in polyphony”,…but let’s say one of my tracks is the bass, and since I’m a sloppy keyboard player, I’d like to force the bass to be monophonic at all times.
Is there a way to do this?

This is simple. In the poly setup, simply do not put an X in the box for each track that you do not want poly for.

facepalm thanks!
for some reason i had thought voices is not the same as tracks in that context.
