Project expenditure batch approval rules be same as GL journal approvals

Summary:

We currently have a requirement to copy the same BPM rules per GL Journal Approval into Project Expenditure Batch Approvals.

GL Journals use a Job Level based approvals wherein when a journal is entered the workflow works its way through to identify the appropriate approver based on amount thresholds.

Finance would like to replicate this same approval rule for project expenditure batches approval too. I have attempted to create the rules but I encountered a validation error when I copied the following syntax in Starting Participant field

HierarchyBuilder.getManager("supervisory",Task.Workflow Submitter,-1,"",""). 

Upon Validation I receive this error
