There are plenty of tools to do this. Regexxer (http://regexxer.sourceforge.net/) is an excelent one. Plus, this is not something you do often. And when you do it, you usually take some time to do it, to avoid messing up your entire project. So really, is it than a problem to open a third party app once in a while for a 5 minute job ? I don't think so. This feature is hard to implement and can wait.
