Recently I've started collaborating with Dysoch and I've started working on Dytech-Power, and i'm looking into ways to modify the cables in between powerpoles and adding my own powerpoles. Now i'm unable to find a way in the API where I can modify and 'add' cables. I have my reasons to want this

Is it possible to add in a later version of Factorio (0.12?) a way for me to add new types of cables (read: give the cable a different color), and give them a special number/string or something so i can script the other properties of the cable?
If there is more information needed as in why I want this feature I'd love to see a PM!
