How can I exchange the warning message text when I switch to Automatic Mode

Joerg_5

I have searched the program directory to find the message text string, but I wasn‘t successful. Can I replace the event message if the internal event signal AUTO1 changes its value? 
I found an answer, which states that internal messages can not be changed.

What can I do to get another warning text?

Many thanks! Joerg
