Gmap + Location Additional Address Field, Option to Ignore when Mapping

It would be a nice feature to ignore the "Additional Address" field from Location Module during the "Find Address on Map" or when saving the node.

The issue encountered is that the additional address is needed, but should be ignored, but included as part of the location, but not the mapping process.

For example, we are including a PO Box as an additional address. The PO Box causes mapping issues because it is trying to locate. If not filling in the additional address field in finds the location accurately based on Street Address.

I'm not sure whether to post here or at Location Module.

Example:

This map is accurate

5337 Hwy 264 East
Washington
North Carolina
27889

and so is this one...

5337 Hwy 264 East
PO Box 1096
Washington
North Carolina
27889

but not this one because Post Office Box is spelled out.

5337 Hwy 264 East
Post Office Box 1096
Washington
North Carolina
27889

There are other instances where we use a Suite # and sometimes get random locations generated. A checkbox to ignore that field would be a great feature. Or in the drop down selection list, the option to "Collect but Ignore for Mapping" possibly?
