How can i handle multiple errors in a collapsed subprocess.

Question 1:
How to display multiple errors in one collapsed sub-process?
Is it right to just put 2 intermediate-error-events on the collapsed sub-process border?

Question 2:
If subprocess 1 and subprocess 2 have the same error (Error 1) do I need to connect the sequence flow with a gateway to handle the error?
→ Error 2 in subprocess 2 has the same outcome as error 1, do I connect it to the same activities as error 1?

No one knows an answer?
