We are using grid with grouping. It always shows the default grouping on field specified in GroupingStore. Is it possible for grid to remember the last group by field automatically when application is started or refreshed.

var grpStoreWorkloadList = new Ext.data.GroupingStore({
reader: jsnRdrWorkloadList,
sortInfo:
{field: 'Status', direction: "DESC"},
groupField:
'IdCase'
});
