this is related to Adding geo location content to node

I'm trying to get a location saved to a node. The Location module supports this, but I don't like the workflow of this module.

It does the lookup after the node is saved, but I would rather do the location lookup before the node is saved. E.g. by having a lookup button, that when pressed, query Google, updates the gmap and lets the user see the location before saving and not afterwards, which causes trouble e.g. if the inputted address couldn't be found.

Any idea on how to address this issue?
