FileMaker 7 Wishlist: Edit Scripts with a Text Editor

I just found out why some FileMaker developers have asked to be able to edit scripts with a text editor. I want to insert a single script step - a Set Field - into over 100 of my scripts for this project I'm working on. If those Scripts were editable in a text editor, I could do a single Find and Replace to get this done in less than a minute. But no, I'm going to spend 1-2 hours doing it one script at a time. Ouch!
