Change columns in grid view for fieldgroups

Hi,

First I want to make compliments for flexicontent. It took some time to understand the basics and a bug in Joomla made it impossible to work with flexicontent on my remote computer. Now with joomla 4.2,  I can test the functionality I need with no limits. Also my compliments for the effort in these forums. However documentation still  is a weak point for a tool like this. That makes it hard to understand the details.
My question:
Is it possible in grid layout for fieldgroup to manage the collumnwidth. For example the magic in flexicontent created the layout in attachment.
   
I want to make the collums maand, maanddeel and omgeving smaller so te column Activiteit gets more space.

Regards
Klaas
