If you use the K2 Import Tool, after selecting the file and importing it, you are taken to a second screen.

The first field to enter is Main Category.

It looks like somehow this is a cache of previous main categories used for import.

The problem is there are so many in the list that is now very challenging to know if I am selecting the correct Main Category.

My customer is using State names as a second-level category, but these state names appear more than once since State is a subcategory of several top level categories.

I tried to attach a jpg screen shot, but the interface does not work.
