I like using Quickdrive scenarios because I can create a Quickdrive consists of my choosing and run them on a route dropping off cars in various sidings as I go. The problem for me is that a Quickdrive scenario sets and locks all non-manual switches for the route it creates often preventing me from entering sidings I would like to use. To get around this I take advantage of the fact that if you are able to get off route via a manual switch, all off-route non-manual switches (although not operable via the 9 key track diagram) can be activated on the ground manually by clicking on the switch machine.
What I do is add a new destination to the Quickdrive which is fairly close to the start point and that is accessed only via a manual switch and is a track I never want to use to avoid ending the scenario . Once you bypass this unused destination on your Quickdrive via the manual switch, you are off path and all non-manual switches become ground operable. The main downside of this is, that without the ability to operate non-manual switches from the 9 key view, you need to be careful of these switches thrown against you since you can only operate them as they are approached.
