How to select Costcenter on the Cost Adjustment screen

We would like to have a Costcenter for the offset account due to Layer Cost Adjustment, so that users can select the Costcenter when registering Layer Cost Adjustment screen and reference it in SLA.
We cannot find the Costcenter or DFF in Layer Cost Adjustment screen, so we cannot enter the Costcenter.
Is there a way to register a Costcenter when registering a Layer Cost Adjustment and reference it from SLA?
