Link 2 outgoing off-page references to 1 incoming off-page referen

[Melissa]

2 processes in my flow chart continue onto the same generic flow, so I have
Process-A, Process-B and Process-Gen.

At the moment, I have ended Process-A with off-page ref "A" and ended
Process-B with off-page ref "B".

On my Process-Gen page, my first process box is preceded by both "A" and
"B".

Is it possible to just have one off-page reference so that Process-A ends
with "A", Process-B ends with "A" and Process-Gen begins with "A"?

I would also to keep the hyperlinks.

Thanks!
