Workflow job type - additional options other than PM

When we setup our workflows, in the workflow jobs, we use the option 'Default Vendor' is the 'Current PM'. Is there a way that we can get another category added, which links to the project's profile, such as Account Manager (preferred) or Project Coordinator? This way, that person would be assigned to that workflow job in the workflow and we don't have to add them at every instance?

Thank you, Mindy
