Template of second level in columns of Datagrid when we have table with reference key to the table2 with reference key2 to next table

Is there possible report column in datagrid from nested tables and references key with second Level at least ?

If we assume that ''first level'' template working well using : ${data.InvokeMetodHandler?.Column} as template and property Ref_Key for declaration of column.
How should Looks declaration property and template if it is possible, for the second Level references key?
