....and the answer would, very likely, be "No".
It's not "complex single" training - it's VP props and Retractable Undercarriage training(in this case). If you already use them then there's nothing new to learn (other than prop settings and how to get the gear down manually).
You should be able to cover all you need with a decent briefing in a classroom. There's no requirement for flight training on any of the "differences" (though probably a bluddy good idea).
If your MEP model(s) include bendy props and disappearing wheels you should be good to go in the single.
A timely reminder, maybe (whilst on the subject), but every model of MEP requires its own differences training.
