GJ make a difference between group and subgroup

Hi,
another suggestion or question, but I didn't try:
the parent groups and subgroups are all named groups.
It would be easier to call the subgroups as subgroups (subcategories as subcategories)
But in translations I don't find a difference. How to change that? (see image)

You'll need to edit the template and adjust its display as needed. There's no string distinguishing the two as they're both groups.
