There used to be a capability, and I don't recall if it was on the inputs or the outputs side of the superblock, you have to try to see which one works. If it were on the inputs you would bring up the connection editor of the superblock of interest. Then you would increase the vector size of the inputs; there should be a number that you can actually increase by typing a new one in its place. It might not be obvious that it is a number you can change. Once that vector is changed, then you can use your left mouse and click between the input numbers where you want to insert the new connection. If it goes where you want, then you have achieved your objective, if it goes at the bottom, then that is a bummer, because what I am recalling must be for the outputs.
Let me know if this helps.
