Is it possible to choose whether to use a User ID or a Name on the project report?

I would like the option to omit names and include only employee IDs on a project report. Names don’t always need to be included when this report is sent to a client. I could use a standard timesheet and hide columns, etc., but the project report looks more professional. Alternatively, it would be helpful if the timesheet could be formatted like the project report, including the log, company information, etc.
