SDP Purchase Order Approval Workflow

SDP Purchase Order Approval Workflow

We have started using approvals for POs and have to manually control the process to send the PO to each approver, one at a time. We are on 7611, which supports multiple approvers, however we cannot use this feature as there is no way to control the workflow process (there is no workflow process). We need to route IT related purchases to a series of approvers, who will only approve if the person before them approved the PO already. This is the classic run in through the chain of command scenario.
 
Are there plans to add configurable workflow routing/business rules to the PO approval process? We would want to control this by some indicator, like a "purchase type", so each type of purchase can go to its series of approvers, but sequentially, and where each one can see who approved the PO already so they can make their decision.
 
Thanks for your consideration.
