Hello Nukleas, thank you very much for the script, it's incredibly useful.

I wanted to ask if you can add an option to make each item in the list of search/replace only run once, ie when it finds the first match and replaces stop and go to the next item.
It would be a very useful option.

Thank you very much for your time.
Xesc.
