Control Smart Lighting Relative to Dawn

I have several solar path lights and use the schedule fearure to turn them on before dusk and then turn them off 4 hours after dusk. I would like to do the same thing in the morning (turn on 2 hours before dusk and then turn off at dusk). This feature doesn't seem to be available so I have to turn them on at a specific time and then off at dusk. It would be nice to be able to turn them on and off relative to dawn.
