Filter to exclude internal subbed episodes.

[Sailsoft2015]

Normally I download episodes without subs, and use this wonderfull tool to find the dutch subs later.

But from time to time I download episodes with internal subs. The hostname of those episodes include ".NLSubs." But MultiSubDownloader keeps searching for those subs.
This takes unnessessary time (surely when searching on addic7ed).

Is there a way to exclude searching for subs that include i.e. ".NLSubs." in the filename ?
