Currently, bill rates are set by user and updates are made on a user-by-user basis. However, we have clients that may have negotiated different bill rates and travel-rates. To work around this, we've created Project Templates with customized bill rates. However, if a person is added to the project at a later date, their personal bill rate prevails instead of the customized negotiated rate. We'd like a way to lock bill rates on a project-by-project basis so that someone that gets added to the job later still maintains the custom bill rate instead of their default rate.
