I apologize for missing that but I rarely look at subjects since so few apply to the actual subject, in my experience.
It's the same thing. I don't know what parts of the code deal with the specials issue off the top of my head. So to do what you want, I would install the addon in a test shop, find the problem code, apply the change and test it. The end fix will probably just be a few lines of code. Finding that code and testing it could take hours. So doing what you want would not save you much in the final cost. I don't know how long that will take so I can't accurately quote it. If you want it done for $20 under the code of the Pro package, I will do that, though it doesn't sound like a good deal to me.
