Message Event or Human Activity

Hi guys, I´m working with a design of a BPM flow where I can have an human activity but if a Message Event arrives all the process must continue even if the human activity is not completed, I try already multiple ways but the human activity never ends, I tried the following.

1.- Parallel Split -> Message / Human -> Notification -> End : Result : the human activity never end, so the process never end even if we receive a message the notification (email notification) never arrives.

2.- Parallel Split -> Message / Human -> Uncontrolled Merge -> Notification : Result : Not the scenario we want, the Uncontrolled Merge by default wait the two task to complete.

3.- (Cancelation Pattern) Subprocess ( parallel split -> Message / Human) -> Terminate :Result : no intermediate messages are posible inside a subprocess.

Any help will be appreciated.

Thanks !
