The way I do it is if I suspect that a connection is close to ten degrees, I enter the wikitree-ID of one of my ancestors, usually my great grandparents (whichever one I think is going to be closest to the person in question)
Then if a connection comes up, I can just add however many steps I am away from the ancestor I chose. In the case of my great grandparents, I would add an extra 3 steps, because I'm 3 degrees away from them.
