BIK Pro-Rata

For Benefits in Staffology (BIKS) is there a way for these to automatically pro rate to the start date of the benefit (e.g backdated from a previous month) as currently we must enter the pro-rated amount then before opening the next period change this again to the monthly amount after the period is closed. This doubles the work for benefits and if we have a larger payroll do this it takes a good amount of time.
