Is it impossible to import a schema into a sub-page?

I have several non-KiCAD schemas for various components that I’m integrating into a single project. They are sub-components of the final. I’d like to import them into individual hierarchical schema pages, rather than manually transcribing them into a wholly-new schema. Is this doable? “File->Import->Non KiCad Schema” seems to wipe out the entire schema in the project.

Open the schematic editor standalone. Import each sheet you want to import, one by one, saving the resulting kicad sheet somewhere. Then open your original project, move the imported sheets into the project folder, and add them as subsheets.

wince I was afraid that’d be the answer. There’s really not a more-direct route?

Well, apparently you are using a source that can be imported into KiCad. For the rest, it depends on the source. For some (eagle I think) you can import a whole project consisting of multiple sheets, while for other sources you may have to import separate sheets. Imports of sheets and the PCB has been working from “altium” for a few years. Work is being done to do the whole project in one go, but I’m not sure what the status is for that at this moment. Maybe it’s in KiCad V9, but I’m still on V8 myself at the moment.
