Is tehre a way to assing Download folder acc to file type?

Hi everyone, I am currently using Firefox on Fedora (KDE Plasma) and looking for a way to automatically route downloaded files into specific folders based on their file extensions. For example, if I download a '.stl' or '.blend' file, I want it to automatically go to '~/3d/downloaded', and if it is a '.gguf' file, it should go to '/models'. Since native application settings only allow choosing one global download folder, using third-party browser extensions feels like a security risk as they require broad file system access(This concern might be unnecessary since I don't know how to decide an extension is safe or not.). On the other hand, running a background automation script (like inotify-tools) feels like an unnecessary workaround for a feature that could be native(I solved it via this method for now). Is there a built-in way or a hidden config in about:config to achieve this by file type? If not, do you think it is worth opening a feature request on Mozilla Bugzilla for native file-extension-based download routing?
