Default mode with USB, charging + USB Tethering?

Is there anyway to make it so that my phone, when connected with a USB Data Cable to a computer automatically turns on USB Tethering? Currently using Cyanogenmod 13. I tried changing the option in Developer Options to RNDIS however it doesn't seem to work (by that I mean it doesn't seem to do what USB Tethering does), and it doesn't hold when I unplug and plug back in.
