[SOLVED] Ad additional Modulposition

How can i ad a new, additional Modulposition ?
I need a copy of Modulposition Main top2 under the existing Modulposition Main top.
Is this possible to do this ? How?
The new Modulposition sholud be visible and selectabel in the Modul-manager and also assign to the Layouts parallel, stacked, double.
I'm a user of Joomla and have experience with Joomla, css and operate with Templates and customize it.
But no experience adding a new Modulposition.

Über eine Hilfe bin ich dankbar.
