I think what you want is to add the flow from the Return Air connector and Fresh Air connector to the Supply Air connector? You could try assigning a parameter to each connectors flow and then simply making the Supply one a formula of the other two. They will probably all need to be Instance Based to work on the fly. I recall doing something simular and having issues with it so make sure you do some testing. Hope this puts you on the right track.
