List Window Type Session (Multi Table)

Hi Guys,

I'm making a List Window Type Session but I can't display the other table fields except the main table that I declared. Is it possible to create a List Window type that consist of fields that came from different tables?

My main goal here is to export the data to an EXCEL file. I can't do this in report because as you know when you create a report it goes with pages which is not I need, I need a report that is already ready for an excel format.

Asking for your support,
