We have the need to use specific action reasons internally, not visible for manager self service. Is there a way that we can do that?

For example - Involuntary Termination, our Payroll team has the need to classify assignment in a different way, and there are 2 specific reasons that they use but they don't want to show them in self service. Out of 12 reasons, 2 has to be use internally.

Is there a way to restrict access to this?
