Start plus end times for workouts

I am a participant in The IRONMAN VR series would ask we add a function to your workout routines. Can we add automated course start and end points aligned to distance. The reason I am asking is that in doing a workout I lose time starting the app and then stopping the app. This may not sound like a big deal but I can lose minutes during a workout when the app takes time at the start point goes long on the endpoint distance, that means loosing many places in the rankings. If you could add start and end distances I could run and have the app start and end at the pre-deteremined point, then I could just run and have the app start and stop. Also include warm delay up to get the app up to speed, it seems to add 30 sec to each work out to start accurate tracking. I would love to be able to set the app distance length, have warm up time, just hit start and have the app lstart logging data after warm up, then auto stop at distance end. As we are all going virtual this is becoming more and more of an issue as I am loosing valuable time, places during each workout. For some reason I set the app to remind me every 1/10 KM, as I run it drifts to telling me at longer intervals, on 10 KM run end I am getting reminders over the 1/10 mark, again loosing time as overrun distance.

Thank You.
