As the doc states, only one end event is currently supported, but it's been on my list with low prio as nobody had requested it. If you can wait a few days, I can give it a try very soon.

Yes, sure. To my mind, this option could be useful in fsm's.

Hi, this should now work (rev 84642 in trunk). Could you give it a try? It's too late for 1.54 so it will make it into 1.55.

I tested it against trunk rev 84986 with vs2012u2. It works perfectly!
