When I create a contact on my Android phone, I can choose to store it to the SIM, the phone or to Google. If I choose phone, is there an easy way that I can move or copy that contact to Google (so it shows up in GMail, for example) at some later time?

EDIT: I'm using the Samsung Vibrant, T-Mobile's variant of the Galaxy S, running Android 2.1. The edit menu for contacts shows options for *Edit*, *Delete*, *Link contact*, *Mark as default*, *Send namecard via* and *Copy to SIM*.
