How to enable credit checking at ship confirmation level in Orchestration Process?

We have a requirement where we want to enable credit checking at shipping level. When we enable credit checking at evaluates at order entry stage and depending upon the Order System Parameter it either allows to

1)Submit the order and order is put on hold or 2) Keeps the order in drafts unless the case folder is approved or payment is received from the customer.

Now we want to enable the credit check to happen when we press ship confirmation button and if the Credit Limit is greater than open receivable the it should perform ship confirm else credit limit is less than open receivable the ship confirm should not happen.
