Activity diagram with swimlanes extend fork bar

Question

In an activity diagram that uses swimlanes and a fork that crosses multiple lanes, is there a way to extend the fork bar over both swimlanes?

In the example, I would prefer if the horizontal fork bar at the beginning and end of the fork extends over both swimlanes
