Payroll run monthly but the cut off dates are specific. URGENT

Payroll run from 1 march to last Friday of month 28 March.. then next run should be 29 March to 25 February etc. It is very important to have the facility to have payroll cut off dates on a month but with different dates. Please advise and URGENTLY look into this

Describe the Challenge

Transition is difficult when we have already informed HMRC on the payroll runs and also clients are annoyed
