php - Google App Engine getImageServingUrl with download file name

Question

I'm using getImageServingUrl method to generate URL to an image and it works nicely along with options listed at List of all the App Engine images service get_serving_url() URI options

I can add "d" option to force file download instead of just presenting it in the browser. The thing is that file name defaults to "unnamed.[ext]" (where [ext] is source file extension). Is there a way I can pass the original filename somewhere to the request?

I can use CloudStorageTools::serve to save file under given name but for example I can't use the image resizing features then.
