combine two schematics onto same pcb altium designer

if you're only ever intended to have one PCB in the project, what use is that!? Might be worth asking Altium themselves about that, see if they have any ideas. (I know OutJob files allow you to select a PCB File to output from, but. So you can generate simulations, schematics and BOM (over all PCBs, anyway) from the master project, but have to go into the sub-projects to generate fab files for each PCB. Might be able to get away with off-page connectors, or something to do with harnesses or subsheets, to 'mate' connectors' nets together so that you can at least use the same schematic files (of course, names have to be unique again, except for nets bridged across connectors, which must necessarily match). best off making yet another project with all that in it (just schematics, no PCB). If you need a simulation over all boards.

Best approach, make individual projects (now designators and net names don't have to be unique), ensure the connector pinouts are consistent between them, and maintain up-to-date STEP models of each board, so that each project has current models of the others with it (assuming you need to view mechanical fit and all that). Somewhere in the docs, it says you can only use one PCB file per PCB Project. Is there a way to 'link' one schematic with one PCB? If no, how are multiple PCB files used? For example, when I make a small change to one schematic and try to update one PCB file, it tries to pull in the hundreds of parts and connections from the other schematics. Altium treats all the schematics as one (which is fine because my part designators and netlabels are all unique), and it wants both PCB files to be duplicates of each other. Today I tried to use a single PCB project and just create one schematic and one PCB file for each 's not working so well. Unfortunately using this method I couldn't easily make schematic changes and verify connections. Then I started to create an entirely unique project for each board. In the past, I would combine the PCBs into the same PCB file and just call out in the fab notes how to separate. How do you easily handle multiple-board projects in Altium? I have a project with several boards stacked on top of each other and I'm having a hell of a hard time.
