Yes, using a program called NeoHacker. You can download it from the files area. You'll need to open the one NCF, copy the code from the button, go into the other NCF and paste the code into that button. I think there are some directions in the FAQ thread. It is pretty tedious if you are doing more than a handful. It is much easier to copy the entire button, and then just change the copied button's graphic to your own.
