Not as such, no. :blackhole: is handled by redirect router. But
RTFM about the "discard" ACL action (which you would find by
searching for "blackhole" in spec.txt).

Sure, you can use a warn ACL stanza to add a header or set an acl_cN
macro that can be tested in a redirect router.
But it would be more straightforward to use a discard stanza in your
DATA ACL:
discard !verify = sender
