Yeah, James, we've got block repeats set up so we're getting the boards built with just pcb fids, and very accurately. I want to be able to build with block fids, though, in case we have any issues with the panelization. It's happened in the past a

I would love to jump on a program like that, but allocating the resources is hard. I am going to need to put together a proposal on why all of this is going to be useful to people that do not understand. I am having a difficult time just writing up
