Hello 

Since I am nearing completion of my first bicycle frame, which is a single speed, I am hoping my next frame will have accomodations for a derauiller. I have been stongly considering using the allotech c210 dropouts, which have plugs like my previous rear dropouts alongside a derauiller hanger. These plugs seem to greatly simplify the process for creating rear stays. I am not seeing the c210 dropouts though in the latest version of bikecad, and I am wondering if they can be added. 

Thanks for the help
