Employer Pension Contributions for Employee not eligible for SMP.

Hello all, 

I hope someone can help and has had a similar issue. By law employers in the UK need to pay employer pension contributions for staff that are on maternity leave. I understand that, however trying to add this to quickbooks payroll is driving me insane. There is no obvious way to do this and I cannot be the only one with this issue. 

I have two employees, one is on maternity allowance paid by the government NOT us, as she wasn't eligible. However we still need to pay her employer pension contributions at her pre maternity leave salary rate. 

the 2nd employee is just about to go on maternity leave and does qualify for her SMP, so her contributions will continue based on her earnings and automatically calculated on the normal set up. However how do I continue her employer pension contributions at the rate we are paying now based on her currently salary not SMP. 

It's really frustrating as no one at QB has been able to help me with this and I've spend 4 hours today on screen share with QB support and they had no idea. 

Has anyone come across this issue and found a solution or workaround please?
