Assigning Brand on batch add import

Is there any way to assign "Brand" on the product batch add import?

I see from DB structure that adding that may be bit tricky!
I only add one category in import and string match is not ideal and brand ID number is bit geeky also.

We have thousands of products so Brands are good to limit displayed products and make easy to find.

Also suggest a global remove/add fields in "batch update page" as been using that to add brand but only want that field.
I'm about to revert to coding or SQL table updates - but just checking I have not missed something!

BTW love this product - very nice, neat and well done - great work - Thanks
