How to locate theme purchase code for specific website among 100's of same purchase

I have purchased around 150 copies of betheme, I need to find the purchase code to a specific site that was in staging but now is live so the url has changed. Now the theme is showing as not registered and some plugins wont update without the theme purchase code. I purchased this theme a while back and have purchased many since. Currently I would have to go to my downloads and download every purchase text file, and plug it into the theme and see if it works. Going to the bethemes envato api purchase code screen, that only shows me the first half of the purchase code so that is useless. Someone tell me there is a way to sort through purchase codes other than spending two hours blindly downloading text files.
