How to have multiple top positions in a position hierarchy

We need to create a new Position and make it a top position in the hierarchy.

The problem is that we can only;

2. either make it a subordinate of an existing position OR

2. make the current top position its subordinate.

We dont want either options. We want to make it a top position alongside the existing top position.

I have tried creating a new hierarchy but is still poses the same problem described above
