DataFlows - Power Query- Group by and Listing the Dates in one column Power Platform

Cheater code:

Table.Group(#"Changed column type 1", {"phil_obid"}, {{"PackagesByOBID", each Table.RowCount(_), Int64.Type}, {"Dates", each Text.Combine(List.Transform([phil_dateshipped], (dtt)=>Date.ToText(dtt, "MMM dd yyyy")),", "),type nullable text}, {"ItemModel", each Text.Combine([phil_itemmodel]," - "), type nullable text}, {"ReturnType", each Text.Combine([phil_returntype], " - "), type nullable text}, {"City", each Text.Combine([phil_city], " - "), type nullable text}, {"ZipCode", each Text.Combine([phil_zipcode], " - "), type nullable text}})

*** AFTER NOTE: 

For the above PFX to work, the column needs to be a "Date" only field. If you need minutes and second, adjust to the time format to work.
