Compact source files should not cause package error when placed in subfolders

I am a teacher and I want to use Compact Source files in my courses. But since the students will have many programs to write, I want to place them in subfolders. Right now, when I do that, I get a compile error that the package does not match the folder where the Compact Source file is located : The declared package "" does not match the expected package "sandbox" Java(536871240) .

Is it possible to add the relative path of the Compact Source implicitly to the classpath/sourcepath while compiling/running/debugging the file? So each time a Compact Source is detected, only the relative path to that file is added, not all path to all Compact Source in the project. An option could be useful, like "Implicitly add relative path of Compact Source to sourcepath : true/false".

Reproduce el error de paquete Java(536871240) con un archivo Compact Source en una subcarpeta y, a continuación, rastrea cómo se gestionan los archivos Compact Source durante la compilación, la ejecución y la depuración. Se considera terminado cuando el archivo funciona desde su subcarpeta sin el error de incompatibilidad de paquete y, cuando el comportamiento está habilitado, solo se añade su ruta relativa al sourcepath.
