New parts editor not available

What you want to do is similar to this one that someone else wanted. The explaination of how I added the missing pins using a text editor for the fpz and Inkscape for the svg may also help you. It is going to be tedious no matter I expect but perhaps easier than parts editor if that is what you are currently using. It could be scripted (with effort ) but as Old_Grey pointed out the coords for the connections are going to be exciting to produce.
