Option for pay date range for pension exports

The current set up is not fit for purpose as the pay schedule for Nest pensions is fixed at 30 days. You can't put in a 31 day range or a 29 day range to match the dates in NEST ( I.E. 31ST March to 30th April). The file will fail to export every time. Staffology should give the option to set the date range, inexplicably it does not currently do this.
