I don't know if this is possible in the mod, but what if you always automatically appended the user name in front of the warp name "behind the scenes"? Except if the user writes out a name specifically, something like name.location in which case "name" would be used instead of the user name.
So essentially you work in your own "namespace" as long as you don't specifically indicate something else.
(The same thing exists in for example C++ where you can either write something like namesp::function(); or begin the file with "using namespace namesp" and then it's enough to write only function(); without having to precede it with "namesp::" as you're already working "inside" that namespace)
