Saving preferences

Hi,
Is there a way in FCP (I'm running FCP 5.1.1) to save all the preferences set in the user pref, audio and visual setting, and system settings and then switching to another set of preferences without forgetting them.
What I mean is that we have a day shift working on one set of preferences/settings and a night shift working on other projects with different settings. Is there a way to switch from one set of settings to another without having to change every little thing every time you switch projects? Is there a way to save them as a set?

Thanks,
Em

Perhaps creating new user accounts for each shift?
