Hi!

In my app I autogroup values as:

```auto
    dashGridOptions={
                        "groupDisplayType": "singleColumn",
                        "autoGroupColumnDef": {
                                "headerName": "Method",       
                                "minWidth":100,
                            }
                    }

```

This also creates a group where only one distinctive row of values exists. Does ag-grid offer a possibilty to group only if there is more than one distinctive row? I haven’t seen such case so far.

Have you checked the upstream docs for what you are looking for? We could provide a Dash example if needed: [React Data Grid: Row Grouping](https://www.ag-grid.com/archive/29.3.5/react-data-grid/grouping/)

I solved it indirectly with:

```auto
"groupHideOpenParents": True

```

It is not a complete solution though because using this soltion together with custom agg functions can cause some (although minimal) grid flickering when adding new rows to the grid.
