How To Perform Pick Release for All Orders/Order Lines based on Order Type?

We have the requirement for the Service items that are coming from the Services module to the Order management module as Sales Orders. The sales orders will have the shippable and non-shippable line items. The client is asking that they do not want to manually do the pick release and ship confirm steps.
They require an Auto - pick release and Auto ship confirm for the same.

However there are other order types - manual orders created in Order management, these should NOT be Auto pick release and should NOT be shipped automatically. Hence based on the Order type We thought to schedule the Pick release program, but it is not possible. Kindly help on the same or is there any other way for this requirement.
