KiCAD "sub PCB's?"

I tried a few different searches on the web and just kept finding page after page after page of "here's how you create a PCB in KiCAD"

What I want to know is, is there a specific way in KiCAD to denote a portion of a schematic to exist on its own PCB? For example, a 500 series EQ where you have two boards that connect together with half the controls on one PCB and half on the other. Collectively, I would imagine you would draw it out all as one schematic, and then somehow break it out across a couple of PCB's.

Alternatively, I guess you could make a "base" PCB schematic, then a "daughterboard" schematic and lay them out separately.

I'm just wondering if there's a specific or "proper" way to do this in KiCAD.

I've been in the same quest as you are but it seems that Kicad will not allow that.

What i do is i make one kicad project for each pcb and put them in a git repository. Therefore i can keep track of evolutions between each project.

Imo, this is the biggest drawback of kicad.

So I'm not just missing it afterall eh? Initially I was thinking there was maybe some feature or option withing in hierarchical sheets...But I couldn't find anything.

That was always how the high cost Mentor Graphics and Cadence schematic and layout packages worked as well, so it is not just a limitation of Kicad. Historically a schematic was tied to one PCB layout, and if you had multiple PCB's you had multiple schematic projects. The projects I worked on always used "flat" schematics, perhaps the hierarchical schematic arrangement might have a way to distinguish that parts of the project were on a separate PCB, but I do not know.
