Yeah - when you're looking at the activity in GC the top right corner there is a little wheel or gear or whatever you want to see it as. Click that and then the second one down says "Send to Device." Click that and your 920XT should appear if you've already connected it to your GC account.
Hope that helps. It should appear after that in your history. I haven't tested it however I assume that should allow you to add PR activities so you don't get a new PR on every new activity.
