Approval Workflow from ePro Stock vs Non Stock items

I'm trying to have requesters order through eProcurement and if it is an inventory item I need that item to go through approvals while if it is a non stock item, I do not want it to go through approvals while on the same eProcurement requisition.  Is there a way to have the approval workflow look at the inventory flag of the item to determine if it needs to go through approvals or not?

Any help would be greatly appreciated!
