Accessing the enitre path in an argument

My question pertains to Services 7.x-3.0-rc3

When creating a webservice you can easily map parts of the path to arguments like so:

That's great if you only want the first part of the path, but what if I wanted the entire path. For example, say I have a url that looks like this:

http://www.example.com/endpoint/resource/some/long/path

Is it possible to map "some/long/path" to an argument, rather than just "some" or "long" or "path"?
