Pin Assignments -- less tedious way?

Thanks for those helpful examples. I exported the assignments from "Assignment Editor" for an example project, and it looks like it's just a Tcl script. I looked through your attached files, and I imagine that at some point you had to reference the schematic and enter each pin manually. Is that correct?

I know it's a one-time ordeal, but I was wondering if these assignments already existed. Particularly, it's confusing to go between the two schematics: the schematic for the HSMC card, and then the schematic for the development board.
