Is your feature request related to a problem? Please describe. Yes this a feature request to enable groupby aggregate list. For a common use case described here : we are trying to use groupby to do list aggregation essentially we have a column for bbox for our data : [x1,x2,y1,y2] . We want to do groupby and list aggregate using a unique id to get a list of bboxes [[x1,x2,y1,y2],[x1,x2,y1,y2],[x1,x2,y1,y2]] ? however when we use groupby and use list aggregate it raise a list of list not implemented.
