Microflow button with optional paramater

Can you setup a microflow button in a Dataview that may or may not use the selection in the datagrid as a microflow setting. i.e. If a record is selected in the datagrid then it is passed to the microflow, if a record is not selected then no value is passed to the microflow. In the microflow one can determine whether the passed object is empty or not Thanks Al

Currently this is not possible, AFAIK. The grid will just show a message about a missing selection. File a change request.
