Custom Orchestration Process - Skip Ship confirm: Bill after Pick Releasing

We would like to create a custom orchestration process where billing is triggered after Pick Releasing to Stage since the product/item does not leave the organization and is just transferred to a subinventory. Items are still tracked so it remains to a subinventory. Will this be possible since the seeded orchestration step is Ship which is the whole Pick Release - Ship Confirm process? Suggestions are highly appreciated.
