How to add new module position in layouts

I need to add a new module position in layouts and cannot figure out how to do it. Currently there is only content top and content bottom and I need to add block1, 2, .....

Per default (= standard installation), there 4 options are available:

1. Column Left
2. Content Top
3. Content Bottom
4. Content Right

But your image shows more options, which means either the system is already modified, or you have installed already an extra modification for that.
Maybe the OpenCart Marketplace has some Extensions to add more positions ..

those are useless positions to add as those already exist.

to use as an example, this one seems to work.

I mean as an example, don't just install the mod or you learn nothing.
