How to export into matching subfolders but under a different parent?

In my workflow, I import into Media/Photo/CameraImport/2025/2025-07-15/filename.arw. Then I develop and rate there, and when I'm done with an event, I select all the ratings >= 1 and Export them as HDR jpgs (or whatever is needed). 

What I'd like is for the exports to go in Media/Photo/Exports/2025/2025-07-15/filename-HDR.jpg, i.e. /Media/Photo/Exports/<original folder>/<original filename>-HDR.jpg, and have those files not be part of the Lightroom catalog. (If I use "original folder" then later I sync the folder to pick up new imports, it'll also pick up the Exports into the catalog, which would be bad.)

Is this possible? I haven't found any way to apply template tokens to the export folder, just the filename. I suppose I could export to one giant folder with everything, /Media/Photo/Exports/2025-07-15-filename-HDR.jpg (filename tokens make that work OK), but that gets hard to manage.

What do folks here do? There's probably a better way. Maybe a plugin like https://regex.info/blog/lightroom-goodies/folder-publisher or something?
