Pause a workout to return a few hours later or next day.

Currently if i need to pause a workout session and want to finish it later there doesnt seem to be a way to do this, its either a timeouted workout or i have to exit altogether. I know i can start the same workout with a new session later and skip through the exercises already done but this seems clunky. if its not already developed and ive missed how to do this can this be a new feature to save a workout mid stream and go back later to finish?
