[Exim] warnings_to type option

Does an option exist in Exim that allows specifying which
addresses can receive "Warning: message delayed..." messages
from Exim?

I thought there might be an option such as 'warnings_to'
(similar to errors_to on directors and routers) which would
default to '*' but it appears not.

Am I missing another option that allows a similar things? If
not, can this request be appended to the Wish List?

Yours,

Ollie
