POI/Favorites editing

[russkoon]

This may already exist and I just missed it. I'd like to be able to update my own POI's and have them show automatically while on the road. Specifically I'm looking for an easy way to dump or at least cut/paste data to a POI file. I see PMN gives up to 500 favorites now, which may be enough if I'm careful, but how can I get all this data into PMN without typing my life away?

Here are some examples of how I would use this:

Cut and paste in all the places where I get bonus frequent flyer miles in the areas I travel.

Cut and paste in the locations of my favorite gas stations (those that take my express wand).

Dump in a database of wifi hotspots from some wardriving sites.
