Silvershop module attribute value csv

I have created a shop with the Silvershop Module. My shop sells courses which have dates and locations. Silvershop comes with export and import batch CSV files which is good. The only thing is it imports products and attributes. But not the attribute values which is the main thing that would be required for me as these are the dates and locations of the courses and updating these manually would take a long time. Anyone here have any ideas if it is possible to import the attribute values too via batch import.
