Ability to customize denied page?

Great plugin! I am using a custom role to do some cool stuff. Thank you!

Question: Can I customize the ‘access denied’ page for a given role (or universally, that would be fine also)?

I assume there is some callback but it was not apparent to me which or where. Or maybe its not possible ??

Tx!
