Question if possible : Can we create nested groups ?

@Lakhtenkov-iv

That will be great to include feature to allow to create nested groups.
We have scenarios where we need to create nested group

Example

-FootLocker (Parent Group)
---FLX User (Child Group 1)
---Non-FLX User (Child Group2)
-----Job1
-----Job2

No files, tests, or entry points are named in the issue. Start by locating the categorized view's group-building and rendering entry points, then determine how parent-child nesting should be represented. Done means nested groups can be created and displayed for the FootLocker-style hierarchy, with coverage for the requested nesting behavior.
