custom screen on multisport workouts?

Sorry for the late response but the data pages for a multisport leg are controlled by the activity profile that's chosen for that leg.

For example, the default Triathlon profile has the following legs:

- Open Water

- Bike

- Run

These all correspond to existing built-in activity profiles on the watch.

If you want to customize the run data screens for the Triathlon profile, you would either change the data screens in the Run activity itself, or create a copy of Run with the triathlon-specific pages and fields that you want to see and select that new profile in Triathlon.

Only issue I see here is that there's seemingly no way to select the Multisport Time field for any activity profile, at least not on my FR955 :/.

(you can tell I don't use the multisport feature on my watch)
