Maps that recalculate during workout

I youse Fenix 6 as my running watch. I want to have a function that recalculate track for me as a run. For example i want to run 46 min in 6:10 min/km. I want the watch to tell me were to run. This is more important for training that changes time and speed. And if I take a pause it will do another track.

Is it possible YOU think?
