Hi Jason,
I'm sorry for the delayed reply, I didn't see the emails to this list for a few weeks.
The answer is kind of. You could export all of your tracks as one track, and then re-import the combined track.
To export all at once, go to Saved, select the Tracks table, and press the top right menu button.
You can't see combined stats natively in the app though.
Regards,
Andrew
