I finally (near the end) have a good solution. A while back, Rob found a program for the Mac, but it only would work for the BS2. Yesterday, the program was updated to work with, among others, the BS2sx. You have to use the older PBASIC because Parallax hasn't released the tokenizer library for 2.5 yet, but they will soon. Hope someone can benefit from this, but I have already...it works great!
