Not yet. You can set options in the Tools>Options>Advanced>Preferencing but the slider doesn't work. And I have doubts how effective the other option is. I do believe it has some effect. In my trials it does seem to filter out some.

You answered just before I was about to add an edit. Sometimes I can direct connect to someone & get 4 star connection, 20 mins later I can re-direct connect but only get perhaps 2 or 1 star connection quality showing. That shows how dynamic the net is with traffic & also about how much bandwidth the other person has available.
