    Something like this?

     

    let
        Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjbUNzTSN7Q0N1eK1QFzDYxBXAsI10DfwAyVa4nEhekFcmMB", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Validator Date" = _t]),
        #"Changed Type" = Table.TransformColumnTypes(Source,{{"Validator Date", type date}}),
        Custom1 = Table.FromColumns(Table.ToColumns(#"Changed Type") & { {""} & List.RemoveLastN(#"Changed Type"[Validator Date],1)}, Value.Type(Table.AddColumn(#"Changed Type", "Previous Date", each null, type date)))
    in
        Custom1
