How can we update/add addresses straight into the database without actually importing a CSV?

We have variables that must be met by our dealers in order for them to be able to show up on the site. So, we are thinking of possible having a script that will run to grab a new CSV or XML once a day that would update these tables.

We just don't want to go through the hassle of doing this if you foresee an issue with something.

Could this possibly be something you could add into the block? I think it would be a great feature.
