Get distance from Fitness Machine Device

I think I know the answer to this question, but is there any way to 'manually' add distance to a SingleGoalWorkout? I.e., I want to make a SingleGoalWorkout with a location set to .indoor, and then add any meters the user has covered from a BLE Fitness Machine Device (exercise bike, indoor rower etc.) towards the workout goal. Is this possible?
