I think you'd end up having to edit any automatically generated script since it might (not) assume you always want to use the same file name, or select the same files, the opposite of what you want, meaning it might save a bit of time but you've still got to have an understanding of the commands in order to tweak the scripts.
For most purposes the Opus commands aren't very complicated. If you can copy and rename some files from a Command Prompt (DOS window) then you shouldn't have any problem making Opus buttons, and Opus helps you by providing pop-up lists of commands and arguments so you can do a lot of button creation just using the mouse.
If you haven't already, watch this tutorial to learn the basics.
(By the way, I have no influence over which features are added so if GPSoftware think it's a good idea it could still be done!)
