mustang IV preset list

I recently purchased a used mustang IV amp. so far it has proven to be a pretty good amp for what I need. I have some questions about it though. Firstly, I found a way to download a BUTTLOAT of presets from the old fuse. they work, I can load them to the amp and everything, my question about it is, is there a way on this amp to rearrange the preset list? there are several preinstalled presets that I like but I would like to put them in a different order. I would like to set the amp up in like blocks of 10. all my rock tones together, cleans together ect. But so far I havent found a way to rearrange them. any help is GREATLY appreciated....Thanks!
