Description

It would be great to automatically pin a column when grouping by the column.

I've tried to implement a workaround with the available gridApi, but I cannot find an easy way to see if the column is already pinned (for example, the existance of an isPinnedLeft attribute) or already grouped.

pseudo-code:

gridApi.grouping.on.groupingChanged(col){
    if(!col.isPinnedLeft){
        gridApi.pinning.pinColumn(col, uiGridPinningConstants.container.LEFT)
    }
...
}

Research direction
Investigate the ui grid source code to understand how grouping and pinning are currently implemented. Look at the grouping service (likely in src/features/grouping) and pinning service (src/features/pinning) for available APIs. The pseudo code suggests checking if a column is already pinned (e.g., via isPinnedLeft property) and then calling pinColumn. Determine if such properties exist or if they need to be added. Consider implementing a new option like 'grouping.autoPin' that automatically pins grouped columns. Review existing issues and PRs for prior attempts.
