Import Items specifying the item-set

I use Import CSV to import items.
I want to import items and associate each of them with a item-set (specifying in each item line the intem-set)

I have managed to import media and associate each of them with an item but is does not seem to work in the same way.

alternatively it is possible to include all items with a specific value in an item-set?

Thanks for you answers

I have just noticed that in the second tab of the importation process, it is possible to indicate one or several item-set form the item imported. I do not have many item-set so it is feasible to import the items group by item-sets.

You can do either of these: you can set item sets for all imported items, or you can map a column to have them vary row by row.
