APM Per-Request Policy Reject - Custom message

When I have a Per-Request Policy end with a Reject, I get the default error page with the content:

Access to this page is blocked.

Access was denied by a per-request policy. 

 

The session reference number: a9f2a37b

 

I'd like to customize this error page but can't find any instructions on how to do so.

 

Suggestions?
