I bought the Garmin Edge 850 right when it launched last year,
but there wasn't a decent data field for what I wanted, so I waited and waited for one to show up,
and eventually got frustrated enough to just build one myself.
The feature packs current power, NP, and average power all into a single data field.
You can configure current power in the settings (1-second or 3-second power),
and if you enable lap mode, it shows lap NP and lap average power, plus lap time alongside it.
(If lap mode isn't used, it shows the NP and average power for the whole activity)
I'm planning to build ones for heart rate, speed, cadence, elevation gain, etc. in the future too.
I'm not a professional, this is just a hobby project, so it's probably lacking in a lot of ways to expert eyes.
Please give it a try and send feedback.
Always ride safe! Thank you.

1. Optimized and tested on the Edge 850, and for now it only supports the 850 and 550.
