Mateusz, it seems this can be achieved using a custom macro to just remap the levels of the 3D cables after they have been generated to match the name of the 3D cable. Our support team has such a tool available to anyone that wants to try it out. Since this can be easily achieved with a custom macro it's not something we will take time to implement in the core functionality of the product itself and so I've set this idea's state to, "Will not implement."

Mateusz, each cable in the project gets a unique name and it's not uncommon to have thousands of cables in a project. Are you actually wanting each unique 3D cable to have it's own level based on this name? I guess you would get thousands of levels as a result.

Can you clarify what you are trying to achieve by having these separate level names?
