external media and wp_handle_upload

Hi,
this plugin is really wonderful and work very well.

I’ve noticed that when a file is importend from an external media it is not processed by the wordpress default function wp_handle_upload.

This function is very important because here any imported file is processed following the wordpress default upload flow.
Furthermore and there are many plugin that hook to wp_handle_upload filter to manipulate uploaded files before using them.

External Media Plugin use the WPUploadMedia_Base->save_remote_file to get file from url (using curl) and then store the file using file_put_contents.

Is there a way to pass the just loaded file to the wp_handle_upload function?

Thanks in advance.
