Check for duplicate episodes and delete the older file

I have a problem sometimes where I will get an episode, and then a proper for that episode will be released and my rss feed will download it again.

Normally I would just use a filter to get rid of everything that I don't want, however i would like to keep the propers.

Would it be possible to have MC check to see if there are duplicate episodes and if there are duplicates found, it will delete the older episode and replace it with the newer one?

So for example if I have

Show Name - 1x01 - Episode Name.mkv (this is the original)

&

Show Name - 1x01.mkv (this is the proper)

would it be possible for MC to detect that there are 2 episodes of 'Show Name - 1x01' then delete the older file, and then rename the new file to replace it?
