Sorry everyone, I remember that I had seen that option a while ago, but
I gave up on it because I couldn't get it to work. I figured out now
that it was because I was using it wrong. I thought that I was
misunderstanding what the feature did(that it didn't do what I was just
asking about), but now I found out it was a problem with my
understanding how to set the regexp variables properly.
It works now.
Thank you.
