Help with configuration of downloaded subtitles.

I love the new feature to automatically download a subtitles withing MPC-HC but I have a small issue.
Right now I have a mkv file with included subtitles inside. They are not "forced" or "default" but they are in english. I have set MPC-HC to look for subtitles in pol eng but even though in this case the program finds both matches it still ignores the pol (and eng) ones and uses subtitles included in the mkv file.

How do I configure MPC-HC to use pol, downloaded subtitles even if the eng subtitles are inside the file?

Edit 1: I see an option to download subtitles if there are none so I guess I can't get what I want?

In this case you can download manually by pressing D.

Can me maybe add an option to prefer downloaded subtitles if they are in the first selected language?

You need to submit a feature request at the MPC-HC bug tracker.
