Multiple prefixes and suffixes in hints

I don't see anything in the docs, but is it possible to have hints entries that distinguish between: userid xx+userid userid@yyy xx+userid@yyy Such that a different hint is given for each of the above forms. The first 3 are easy. The last one is the issue. I am guessing that an entry along the form of: DEFAULT Prefix == "xx", Suffix== "@yyy", Strip-User-name = Yes Hint = "4th-form" would be used.
