Position hierarchy and workflow

Hey Everyone,


I wanted to know if there was a way for one individual to report to two different individuals in the position hierarchy. The reason for this question is that we are currently using the position hierarchy to drive workflow for the purchase requisitions. We want to drive who the requisition gets approved by based on a project manager field that we added. Currently only one person creates the requisitions. I'm not seeing a way to split how the document gets routed if we continue to use the position hierarchy without completely revamping the way that these documents get processed. Has anyone else run into a similar issue? Does anyone know of another approach that may help? Thank you in advance.
