I'm not sure if this answers your question but in an EasyEDA Project you can have a schematic spread across any number of schematic sheets from which you can generate a single PCB for all the sheets. You can do **Convert to PCB** any number of times and generate a different named PCB each time by saving them with a different name. Subsequent to this, you can do Update PCB for any PCB because you will be asked which PCB to update. You cannot however have different schematic sheets in a Project and convert each sheet into a separate PCB because on doing **Convert to PCB** all the sheets in a project are assumed to go onto the same PCB. Given those constraints, here's what I think you will need to do: 1. Split the design into separate schematics, one for each PCB. 2. Put each schematic into a separate Project. 3. Convert each of those schematics into PCB. 4. Then you will have a complete Schematic, BoM and PCB each in it's own Project folder.

@andyfierman Thank you, I kinda hoped that it would be posible while having it all in one project (because it is one project) or filter them out after the importing.
