Import P45 marked as sent alongside leave date - Freelance payroll

Hi

I run a freelance payroll and do not need to issue P45 and want to be able to upload the P45's marked as sent. I can see this was meant to be actioned in 2024 and it still not working.

Can this be something that is updated on your software as we have a high number of starters and leavers on a monthly basis and do not want to update this manually every month.
