Files Download on both local and AmazonS3

Hello,
I have successfully configured AmazonS3/Cloudfront for audio streaming.

Now, I need to upload PDFs, and in order to speedup the creation of a post, I was thinking to use this plugin

Everything works nicely, but I have an issue with the mod rewrite, because of course the system will redirect to Amazon (where the file has not been uploaded).

I was reading the documentation and I found this:
Specifying storage location option dynamically:
… /wp-content/plugins/s2member-files/s2member-file-storage-[local|s3|cf]/example-file.zip
… /wp-content/plugins/s2member-files/s2member-file-storage-cf/example-cloudfront-file.zip
… /wp-content/plugins/s2member-files/s2member-file-storage-s3/s2member-file-inline/example-s3-file.html

I’m not sure if this is going to fix my problem.
Can I use both Local and AmazonS3 storage?

Thanks
