Hyperlink in ErrorMessage field of cross-parameter constraint

In Simulink, I'm creating a masked subsystem with a cross-parameter constraint. There is an ErrorMessage field so you can display something useful if the constraint is violated.

How can I create an error message that links back to the subsystem when the error message is displayed in the Diagnostic Viewer?

If I leave the ErrorMessage field blank, the default message does link back to the subsystem, but the text is generic and not as descriptive as I'd like.

Thank you.
