Plugin requires post save, but what about .csv import

I’m trying to create a business listing with 33k records, including geo search. I already have the latitude and longitude data for each entry that I plan to import through a CSV upload. There is a plugin (Geo Mashup) that will copy this data from the geo_latitude and geo_longitude fields line and lets me add a proximity search function to the website. However, to take the data from these fields, each entry has to be opened and saved for the data to be processed. with 33k entries that isn’t an option.

Is there any other way to accomplish this for each posting in my WordPress install?
