That is more difficult. The current way it works is based on the
injected type deciding which method/constructor gets used
(by matching the passed types to the parameter types).

What you are trying to do is the reverse which currently has
no infrastructure to support it.

It is also an unsolvable problem in general:

e.g.

  | public class MyClass
  | {
  |     public MyClass(Type1 type1) {}
  |     public MyClass(Type2 type2) {}
  | }
  | 

Which type should I use Type1 or Type2?
The only way to resolve it would be:

  |          <parameter class="Type1"><inject/></parameter>
