Is there an simple way to remove missing episodes?

[BigRonDon42]

I screwed up and forgot to untick missing episodes fetcher for one of my libraries. When I use the search function all of these missing episodes appear in the results which annoys me. I have no intention of ever grabbing these episodes so they will remain "missing".

I would like to know if there's a non-painful way to remove them all.

The only way I know of is to rescan and "replace all metadata".
