This issue proposes an enhancement to the MapUploadedFile

Specify Upload Directory: Allow developers to define the target directory for uploaded files using a directory option. This provides
flexibility in managing file storage locations within the project.

Generate New Filename: Enable the generation of unique filenames during upload. This avoids potential conflicts and improves file organization.

Example

    #[Route(path: '/user/picture', name: 'upload_route', methods: ['POST'])]
    public function changeUserPicture(
        #[MapUploadedFile(constraints: [
            new Assert\File(mimeTypes: ['image/png', 'image/jpeg']),

        ], directory: '/public/uploads'
        )] string $pictureName
    ): Response {
       // $product->setPictureName($pictureName);
    }
