Reduced Pay due to Sickness Schedules made clear on payslips

If pay is reduced due to a sickness schedule, rather than pro-rating the salary, please could the payslip show the full salary and then deduct the relevant 'unpaid sickness'? This makes it clear why there has been a reduction in salary, especially if the employee doesn't qualify for SSP.

For example, an employee is paid £100 per day, works 5 days per week (salary of £500pw) but is sick for 3 days. Instead of showing on the payslip as 'Salary: £200', please could it show as 'Salary: £500; Unpaid sick leave: -£300' giving the total gross of £200.

Even if it is added as an option rather than the system defaulting to it, as we manually calculate the SSP so we can do it this way because it's clearer for everyone to see the calc process and raises less queries from the client
