Sebastian,
CRM Advanced Find is not capable of doing that. However, you could create a dynamic worksheet and then modify the query to display that information in excel.
Here is a blog post I wrote that has a video on how to edit the query, etc.
The steps are:
- Run an advanced find in CRM
- Export it to Excel as a Dynamic Worksheet
- Open it, save it as an excel file.
- In Excel 2007, Click on Data in the ribbon, then Connections.
- Click Properties
- Click on Definition tab, edit the query
- Click ok, then click close
