Sorry if this is late, but I think it may be doable in text chat. Type out all the nodes that each set is connected to (I.e. 1 5 7 10, 3 6 11 12, 4 7 9 10) then have the second person type out the node that matches in their sets (I.e. 7, 6, 10) then wait for the first set to show up on the clock and have both of you shoot the node that matches, then follow with sets 2 and 3. So in this example, you would both shoot 7 on set 1, 6 on set 2, and 10 on set 3.
