How to reopen a case automatically when a new email is received(using Process Definitions)?


I'm using Sugar 8.0.3 Enterprise, how can i re-open an existing  closed case(Status: Closed) when a new email imported via email to case functionality has the matching Case Number[Case Macro]  on the subject ?

I note that Emails is not a module that can be configured for the Process Definitions(SugarBPM) in Sugar 8x , however it is on Sugar 10x
