Yes I agree... being able to chain overhaul orders in with any regularly cycled order would be really nice.
I still like the idea of setting up a patrol and having the ship go and do "Refuel, Resupply & Overhaul" and then resume their cycled order from their last point. This would make things the most simple for players in general as you don't have to sit and count roughly when a ship need to do overhaul during a cycled order chain.
I do hope we can get some automation in regard to patrol orders... I think we could need them for both parasites and regular ships. A ship that dock with hangar should also be able to automate patrol order in the same way in my opinion. This would make it easier to have patrols stay on station around a carrier without you having to worry when it needs to go back and rest, refuel or whatever... it will just return to patrol when it is done automatically.

I missed that Steve already added this mechanic to next version... great news...
