How to - OfficeMail OFMA using Settings Group to assign different stock to mailpiece is not possible for a job

OFMA's Settings Group is not designed to assign different stock to mailpiece for a job.
Each submitted job would/can only have 1 type of stock for sheet 1, same type of sides (simplex/duplex), B&W/Colour, Service and Envelope type, etc.
OFMA can only split mailpiece, but it cannot assign different stock for mailpiece's sheet 1 individually.
User would need to split/separate mailpiece that use different stock at earlier stage; before submit it to OFMA.
