Distinguish force download for embedded/external subtitles

[Ganfoud]

Hi
I've been using subliminal for a while now and love it

However, I was wondering if it was possible to distinguish the force download option depending of the existence of embedded or external subtitles.
The explanation for this is that I force download subtitles for files newer than 2 weeks, in order to download the latest subtitles for this file. However, if there are embedded subtitles, they are usually the right ones, so no need to download additional external subs...

I don't think this is currently possible, and it is not a big deal to manage since I only have to select the embedded subs in the player, but I thought it could be a nice enhancement to subliminal!
