jQuery Grid Plugin - jqGrid

After grouping, is there a way for expand/collapse icon of current row not automatically expand/collapse all of the subgrid's rows? Just leave it alone as it was.

$('#test').jqGrid('groupingGroupBy'), 
   parmColumnName, 
   {
       groupCollapse: true,
       groupField: ['name']
   }
);

//Original setup after playing around with it. (See X5 under BMW)

//Collapse the grouped Make (BMW)

//Then Expand the grouped Make (All of the model are expanded by default, I do not want it to change and I want it to look like the original snapshot above)
