Add Date To Downloaded Videos

Downloader is great, but when catching up on a channel, it would be good to keep videos in the order they were uploaded. Not all playlists are numbered, so could an option to add the date the video was uploaded to the filename be added?

For example
SomeVideoFromYoutube.mp4 uploaded on 2 April 2016 would download as

2016-04-02 - SomeVideoFromYoutube.mp4
