Adding tax codes in the future

We have some clients that are not very good at getting us the information for linking the payroll to HMRC for tax updates.

Due to this we have to manually put any tax code changes onto Paycircle. As we're reaching the end of the tax year I am getting some tax codes effective 6th April 2024. I can't add this to Paycircle as they must not go beyond the current month so I have to save these notices and set a reminder to do it in Aprils Payroll.
