@D.J.Petrou the RangeTech only can do what the app provides. In this case that is the PractiScore app.
The automatic pre-set of the stage-specific par-time setting is supported on several Bluetooth-enabled timers for all scoring types that have the par/max stage time setting in the PractiScore app, at least on Android. See more details at Bluetooth timers supported in the PractiScore app for Android
