Yamaha DTXpress/DTXplorer/DTXtreme

As I just bought myself a DTXP III kit I am now starting to explore
its features. Here are two questions that probably easily can be
answered by experienced users:
- Is there any possibility to record just the metronome click to one
of the two tracks of a User Song?
- How can I adjust (separately) the trigger settings for the three
zones of the snare pad?

For any advise I am greatful.
