Is it possible to add a mark up in Project Contract Billing based on Tasks only?

Summary:

We're trying to add a mark up for specific tasks, however when we are creating the Bill Plan with Bill Rate Invoice method it forces us to select the fields for Person name, Project Role, Job and expenditure type. We do not have rate schedules for labor in our current process, therefore we do not have any information for person name role and job, we only need to add the Mark up percentage by task only.
