Runtastic App - Load Workout into MFP from before apps were synced?

Sillyna511

I just did a 15 minute walk with the Runtastic app, and I just now synced the MFP app to it - but I can't figure out how to upload the workout I just did so it shows in the MFP diary. Is there a way to do it? Or will MFP only automatically sync with workouts done *after* the 2 apps are joined?

Thanks!
