Services: REST API, custom URI path for services/session/token?

Hi -
Is it possible to access the CSRF token resource (services/session/token) on a custom API route? Let's say I have an endpoint exposed as "desktop/rest" and a typical User route might look like "desktop/rest/user/login" I see the "token" resource available as "user actions" but when I try to GET it like "desktop/rest/user/token" or any derivative of the out of the box session string ("services/session/token"), rather than a session token, I get a message about missing User Id. It is routing to the User controller.

Thanks
