Is is possible to change the verbiage on the standard "Sorry, this page isn't available" error page in APEX? This is the one you get when a user enters a url to a page that does not exist in an application, like this:
To reproduce this, for example, if this is our valid APEX application url:
https://apps.mycompany.com/ords/myworkspace/r/tsat/home
And a user enters a non-existent page name (likely one that previously existed but where we have since removed, and therefore breaking the user's saved bookmark), something like this:
https://apps.mycompany.com/ords/myworkspace/r/tsat/blah <- There is no "blah" page in the app
Then the user will get "Sorry, this page isn't available" error page above. Is it possible to customize the text on that error page?
