I had a similar issue with a sandwitch-board (i.e. two pcb mounted with risers). The trick is to use a single pcb file with all your boards drawn into it and declare the joining points (connectors, risers, whatever) as modules (like the CONN_ parts). Of course you have to manage manually the pinouts of these connectors to make them match! It is actually easier to build them later since you only have to submit *one* gerber/PnP set instead of three! You could also ask the manufacturer about how he would like the board aligned to ease panelisation and where to put scoring/rat-bites indications (but, anyway, they will have no trouble separating three boards from the same gerber set).
