Is it possible to configure kinematic objects, so they don't interact with each other?

Is it possible to configure kinematic objects (in my case, player capsules) they don't interact with each other?
I don't need colliding capsules and also it reduces performance. So I want to find a way to only calculate collisions with static objects.
I looked through the documentation and did not find such functionality. Perhaps I was looking in the wrong place? =)

Have you tried using collision layers and masks?

[William-Godwin]

Oh... I knew about layers, but I didn’t think that masking was also supported. Ok, sorry to bother you!
Thanks again for the answers! And for a cool extension! =)
