Scheduling outdoor lights to temporarily override motion sensor

I am sure that there should be an easier way to do this?
I have outdoor garden lights on a motion sensor, but I want to override the sensor so that the lights are on in dimmed state from 20:00 to 22:30 every evening unless you trigger the motion sensor when the lights will go full brightness; then after the scheduled event the motion sensor works normally.
The only way i have found to do this is to create a schedule ie garden lights (dimmed) on 20:00 - 22:30 Then to set up the motion sensor for motion timeslots 20:00 - 22.30-(Full brightness) & 22:30 - 20:00 (Dimmed). And then for No motion timeslots 20:00 - 22:30 (Dimmed) & 22:30 - 20:00 Dim & switch off.
If this could all be done from the schedules menu/tab it would make things much easier, but as there are no action options it is not possible.
