Have multiple groups in Creator Report

Have multiple groups in Creator Report

Hello,

i am trying to create a overview based on multiple reports.
The problem im having is that each report has got different Columns that would just be empty for the other reports.

Example:
Report Hardware
-company
-type
-manufacturer

Report Software
-company
-name of software
-version

So if i put them together i have to have 6 Columns from just 2 reports, at the end i would have 50+ Columns.
They are grouped after the company so you get an overview.
Is there any way to create sub-groups with different Columns?
