What is the easiest way to add a new contact to an existing Google contacts group? Let's say I'm adding a new contact and it's a long lost family members so I want to add them to my custom "Aussie Family" group within my Google account. There appears to be no easy way to do this. I have to log in on a PC to actually achieve the grouping.

I recall reading a similar question somewhere (which I now can't locate) which indicated it's not possible using the built-in contacts manager, so, if that's the case, I'm looking for the best way to do it via an app.

I'm using Gingerbread (2.3.3) on a Samsung Galaxy phone (kernel v2.6.35.7).
Thus far, there appears to be no answer. The best alternative appears to be that you can log into Gmail on a PC and add your new contact to an existing group. Will change the answer to this question if a valid answer pops up.
