Custom Group Format in columns

Hello everyone,

i’m playing around with custom group format since i need some more functions than the standard aggregate functions. The problem is that if i’m using a custom group format all my informations are written into a single row but i want to have the informations in seperate cells. As an example:


this is what you get if you use a custom group format.

I linked an image of what i want to achieve as an attachment.

Is there a way to create multiple cells using a custom group format?

Greetings,

Unfortunately it is not available to split the group row to align the grid cells.
