Blocking calls after hours for cell but not physical phone/desktop app

The afterhours option is great. I want to use the phone app, but don't want work calls afterhours. The problem is this is a global setting. So if I am working late at the office, I can't get calls unless I remember to turn off the afterhours. It would be great to have the after hours seperated between mobile app (so I don't get calls outside the office) and physical phone/desktop (so I can get calls if I am working late)
