Is it possible to rename submixes in MPC software?

I searched around with no luck here or on Google. Are the submixes unable to be named? If so, Do you guys have a system, then, if not? I'm thinking I'll have to write down what my submixes are to keep track them at first. Thank you.

No. There isn't.

I run it like this:

1/2 Drums
3/4 Strings/Synths
5/6 Bass Sounds
7/8 Sound Effects
9/10 Vocals/Vox/Speech
11-16 are flexible depending on projects.

I would love to be able to route all my effects returns to these spare submixes for further control PLUS have them completely automatable so I can manipulate every plug in through the course of a song or automate the volume levels, pans, mutes of those submixes or effects returns.

This makes this thing perfect for me but I digress.

Thanks for the reply. I'm confused, though, I thought there were only 8 submixes? Also, can I assume there's no multitrack out as a plugin? Man. Guess I'll have to get used to getting my drum mix right first go.
