In Fablink Pro 2005.
Picture this. You make a panel of small inch square circuit boards in Fablink Pro. Some time later you need to up-issue the individual board artwork and re-issue the panel. Rather than rebuilding the whole layout of the panel from scratch it would seem sensible to be able to replace all the instances of the old revision of the board with the new instances of the board (a different file). It is, after all, exactly the same size and shape.
There doesnt seem to be any mechanism to do this. Am I missing something obvious?
