Hello titleblock-a4 etc. in gschem have fields in them - you can reference to some place in the schematic say by B13 or A7. I suggest that a function be added into some tool (gschem, gnetlist) which for each part computes such a field. It could detect a presence of the titleblock and then compute from the coords. Don't insist it but think it can be a good fun for the future ;-) Cl<
