[Feature] Combine Stack Classes

[mgsimon]

It is difficult or impossible to get badges for which a longer rides is needed if Peloton supported training sessions are used only.

Combine stacked classes of same type like ride to get a better view about the amount of training and to get badges for longer rides.

Like:

• 10 min warm-up ride
• 30 min music ride
• 15 min climb ride
• 10 min cool-down ride

with the possibility to convert this stacked classes to one Garmin bike training session in total 65 min.

Maybe with additional check box for a combination which could be identified by the timestamp.
