Is it possible to allow all requests to a protocol?

[David Cobb]

Is it possible to allow all requests to a protocol (or otherwise use a wildcard of some kind)? Some third-party applications use faux-URLs that don't have a traditional structure (e.g. "nxm://Skyrim/mods/######/files/#######"), and RequestPolicy forces me to allow these requests one-by-one when it'd be better to just allow the whole protocol.
