In a suitelet sublist, can you create dynamic url fields (columns) like you can in a "normal" suitelet list? Like list.addColumn({...}).setURL({...}).addParamToURL({param: 'id', value: 'internalid', dynamic: true})? Or for sublists, can you only have a 'static' url field where all the rows have the same value (i.e. 'Edit', 'View', etc)?
