How To Mass Add Category (Without Replacing Existing Ones)

Hi,

Is there any way to add single category to a large number of products? It seems impossible through bulk upload, as all existing categories are being overwritten with the new one. Is there any trick to append one?

Thanks!

If you are asking can you ADD a second category to an existing one then the seperator used to be ///

categoey1///category2///category3

but I haven't imported new ones for a while

you can always add a number of categories in the admin and export it to see how its laid out

How many categories do these product have? If only one, you can add new category to the Secondary categories field. If more, you can export products, open file in Excel, add new information to Secondary categories columns in bulk and import this file back
