I read the wiki a few times but I'm a bit foggy on the Tab delimited spreadsheet column headings.

I'd like to add additional Selling Copy and was wondering if I can simply add my own headings as long as they conform to the existing structure.

There's already a v_products_description_1 , can I add v_products_description_2 or am I limited to what is on the tab delimited txt file created by Easy Populate?
