How to use the attrName of the **outermost** `lib.types.lazyAttrsOf` inside the arguments given to a child `lib.types.submodule`?

Inside a configuration given to a lib.types.lazyAttrsOf lib.types.lazyAttrsOf (lib.types.submodule ...)-typed option, how do I use the attrName of the outermost lib.types.lazyAttrsOf inside the arguments given to the lib.types.submodule?

Note that using the attrName of the innermost lib.types.lazyAttrsOf is possible through nixpkgs/lib/types.nix at e59d0ed541ffb2cfe06d8d07664ff6eca7a5b895 · NixOS/nixpkgs · GitHub,
e.g., the nix repl evaluation of the following, after bringing lib into scope, is "qux":

(lib.evalModules {
  modules = [{
    options.foo = lib.mkOption {
      type = lib.types.lazyAttrsOf lib.types.lazyAttrsOf (lib.types.submodule ({name, ...}: {
        options.bar = lib.mkOption {};
        config.bar = name;
      }));
    };  
    config.foo.baz.qux = {};
  }];
})
.config
.foo
.baz
.qux
.bar
