remove indexed file

[eldaiquiri]

You might think I am crazy but I have renamed all of my files in the same format (artist - title). This makes creating a song book a snap. The problem comes when I want to replace a song with a better version. I delete the song from the edit song menu, then I delete the file from my hard dive and replace it with the better version. Since the file has the same name and is in the same location, when I try to import it it shows up as being indexed so I can't see it on the list unless I click on the (show indexed files) tab. If I do this I will have to index all the files again until the one that I want shows up on the list. Is ther a way that I can (un index) a single file?
