Retention Payments via FI and/or MM

Hi,

I am looking at retention payments via FI and MM. I managed to understand the steps on FI creating a special GL and map it to my vendor reconciliation account to be able to have a list of retention payments. I also created a Instalment Payment term and assign it to the vendor.

but ..

Is it possible to pay the vendors via MM using MIRO, with special GL's? If so? How do I do this.
