You can't do that sadly. What I usually see done when this is needed is one of two things:
* Some sort of dynamic structure, like a map or hash or list, without predefined contents.
OR
* Use a script to build the structure out of some sort of data file, and also build an array which describes its contents.

First thought was:

struct two;
}
struct two
{
three;
}
one->two->three
