I am in the UK and I know that you can select the whole country as a territory then export all the postcodes at area, district or sector level. I am sure somethign similar is achieveable with the US version and then you could link to the export. It is slow because you have all the data in mappoint and it does really make the file bigger and more cumbersome. Try exporting and linking back to the territories - I know on many projects for my own work this has speeded things up endlessly.
