Is it possible to add a launchMode(like Android's Activity) params at Route definition?

I hope a ChildRoute could be single instance for the APP. When I using Modular.to.pushName('/example/path'), modular will find the existing page in the stack and move it to the top, or create a new one if it is not exist.

So It's perfect if there is a parameter in r.child() to set the launchMode.
