Hello Michaeleba,
Before you edit the region to change switch stands you should be aware that some of them are skittish. If you insert a spline point somewhere nearby the things will hop around wildly like a March hare, showing up far away, and searching for the critter is no fun. The standard Auran levers, hideous as they are, tend to stay put, with rare exceptions. FWIW you would probably do best by suffering the default levers until you figure you have things pretty well set, then do an asset replace or replace them one at a time.
