Training with Power Zones

Hello,

I'm interested in the TwoNav Cross mainly for usage as a GPS and bike computer on my MTB.

As I want to do some structured training (with heart rate monitor and power data), I would like to configure the data fields in a way that gives me the necessary information.

In the online handbook I found heart rate zones as a possible data field, but are there also power zones? Or is it possible to configure them myself in some way, so that I have a color-coding for the different zones or something similar?

Thank you for the information!
