Can I put a FitContributor value in History/Activities?

I managed to make a "session.createfield" value (:mesgType=>FitContributor.MESG_TYPE_SESSION) in an app, and had the value shown in Monkeygraph.

As I understand, I can see this value too in Garmin connect, but at least after sideloading I could not find it.

Three questions:

1. I would like to display the self-created value on the device under History/Activities, but do I understand correctly that this is not possible?

2. Is it normal that I can't see the value in garmin connect after side loading, only after publishing?

3. Can I see the self-created value after beta-publishing?
