Populating Sales Channel Field Through Customer Information

Summary:

Hello,

We have a DFF created under the receivables module in billing which is currently being used to fill as an additional attribute for "Sales Channel." This was created to make a link between the sales channel and the customer on the module.

What we are trying to do now is populate the sales channel field on the sales order header depending on the customer using the DFF that was created in receivables module. Since the sales channel values are managed under "Pricing Lookups" would it be possible to extract this value from the DFF in receivables module, and populate it in the sales order when the customer is selected, and if it is possible, could we do it through configuration on Fusion or would we need to use an API?
