Auto-add static field when inherit // mixins, templates?

[MarisaLovesUsAll via Digitalmars-d-learn]

I found a rough solution. It's not ideal and I still want to make 
autoinject, but it works.

mixin template Manager(T) {};
class Component {};
class Sprite:Component
{
     mixin Manager!Sprite;
};


1) How to make mixin inject automatic?
2) If it's impossible, how to use "mixin Manager;" without 
"!Sprite" ?
"mixin template Manager(this T) {};" isn't working.

Regards, Alex
