Drawing Subprocess Boundary Interrupting Messages

Hello,

I am new to BPMN & grateful for advice regarding a interrupting message event attached to a subprocess boundary.

The exception sequence flow for the interrupting message should complete & rejoin the subprocess at the point it left.

Firstly, is it correct to join the exception sequence flow back to the subprocess?

Secondly, how do I draw the join so the sequence doesn't start at the beginning of the subprocess again?

Many thanks in advance.
