To Default the Cost Center to Withholding invoice from Primary or parent invoice in AP

We have Withholding Tax that is being applied on invoices

At the invoice level we are defaulting cost center to withholding Tax line (I have modified SLA to bring same cost center of related invoice distribution to withholding tax distribution) this is working fine

when Withholding Tax is applied, system is creating withholding tax invoice automatically -->this is also working fine

system is creating invoice distributions in withholding tax with default cost center

i want to populate the same cost center that is being populated in primary invoice

Please let me know if anyone know how to update the SLA to get the desired effect.
