I don’t think there is a way natively in KiCad. KiCad is really for creating a single board from a single schematic. Doing any more than that is a bit of a kludge. That said, someone here on the forum has published a stand-alone tool to add tabs with mouse-bytes. See this thread:

Tool for creating panels in pcbnew

I’ve just completed a tool that create the tabs with mouse-bites between pcbs in pcbnew, it’s on gitlab here: https://gitlab.com/dren.dk/kicad-util The workflow is quite simple: Start pcbnew outside of a project Append and place completed boards with at least 3 mm of spacing. Draw lines between the boards in the Eco1.User layer where you want tabs to connect the boards. Run my kicad util with the panel option. Open the newly created output pcb file and re-fill zones or run DRC or whatever els…

Hope this helps.
