Flow Bus to collect common flow destinations

I frequently spend a lot of time concatenating Merge element in Micro and Nano Flow.

For example:

• Collecting all the custom error handler to a common variable setting or to an unique  end event (this allow an easier extraction on sub flow)
• Collecting flow from decision element that merge to a single Activity.

Using single merging point can mess up the readability of the Flow.

A flow bus element (A thick line that implements the same logic of a Merge) can provide a time saving solution.
