Laying associations with Excel importer

Hi guys,

The situation is as follows:

Before the import, a batch object is created which can be given a name.

During the import, another object is created for every row.

This created object is associated with the batch object, but I don't know how to configure the Excel importer in such a way that it automatically lays the association with the batch object that is made before the import happens.

How do I do this without having to add another column in my Excelsheet?

Thanks in advance.
