Decrement or Increment month

[soongsta]

Hi There

I am wondering if its possible to do something like this in ranges

function cb(start, end) {
    $('#reportrange span').html(start.format('MMMM D, YYYY') + ' - ' + end.format('MMMM D, YYYY'));
}

$('#reportrange').daterangepicker({
startDate: start,
endDate: end,
ranges: {
'Today': [moment(), moment()],
'Yesterday': [moment().subtract(1, 'days'), moment().subtract(1, 'days')],
'Last 7 Days': [moment().subtract(6, 'days'), moment()],
'Last 30 Days': [moment().subtract(29, 'days'), moment()],
'This Month': [moment().startOf('month'), moment().endOf('month')],
'Last Month': [moment().subtract(1, 'month').startOf('month'), moment().subtract(1, 'month').endOf('month')],
'Decrement Month': [moment(start).subtract(1, 'month').startOf('month'), moment(end).subtract(1, 'month').endOf('month')]
}
}, cb);

var start = moment().startOf('month');
var end = moment().endOf('month');
cb(start, end);

Basically, keep on decrementing or incrementing the current displayed month
