ErgData - Pull historical workouts from PM5?

[vandoj]

I have Erg Data working properly and when I row with it connected to the PM5 it will sync sessions. However, I had several workout sessions on my rower before I downloaded Erg Data. In the info about the app, it suggests that Erg Data will pull the history off the PM5 and sync it with my logbook, and I can't figure out how to do this. So, is there something specific that I need to do to tell Erg Data to pull workouts from before I got the app and sync it with my logbook?

I know that if you download the workouts to a USB and upload via a PC to your logbook, Ergdata will then sync with that info.

I don't know of any way to sync just using Ergdata. There might be, but I have never found it is an option
