I used the bcm import wizard to import a CSV file. I could only import one category. Is there a way to import two fields as two categories?

or is there some code sample for moving field values. What I'm thinking of doing is parking this second category in a TTY or other field I'm not using, then run code to move it to categories field.

Or should I just import them seperated by a semicolon ";" -- will that automatically make them two catehgories???

thanks!
