Is Kicad v9 can deal with hierachical sheet in hierarchical folder?

Hi,
I’d like to use hierarchical sheets in hierarchical folder but I didn’t success.
My main sheet is in the root project folder.
I have a SCHEMATICS folder under root project folder.
Another folder under SCHEMATICS, called CPU.
Inside CPU, I have multiple sheets, one sheet ( called IMX) use the others in hierarchical mode.

If I create a hierarchical sheet in my main sheet to IMX sheet, Kicad ask me to create link to existing file and use relative path, I accept this.
BUT relative path are strange ( beginning by home/xxxx/path_to_sheet (note the missing ‘/’ at the beginning ), and not seems to be a relative path from my project path.

Is Kicad v9 can deal with hierachical sheet in hierarchical folder ?

You could probably use the project variable ${KIPRJMOD} like this: ${KIPRJMOD}/folder_name/sheet.kicad_sch

I have not done this before, but I usually do it for 3D models for example.
