Job Mapping with Overtime Multiplier

I would like to use a job mapping to map multiple HCM jobs to a handful of Project Jobs.

When I do this, will the system use the Project Jobs I am using for the Overtime Multiplier application, as in

If my project job is setup to attract Overtime, then the overtime multiplier should calculate in both Planning and Costing?

I have gone through documentation and there is not anything that addresses this specific combination and I'm not observing this behavior in my testing.

Thanks in advance.
