Well maybe but I don't think so - the presets are in the form of .oms "packages" which contain thickness, drying time, ink limits, icc profile, and the paper name that will display in the printer's on board paper list. This name is different from the name of the .oms file so I don't think changing the name of the oms will work. Also, I'm nervous about experimenting because last Christmas I loaded an oms file provided by a big name paper manufacturer and it corrupted the firmware on my old z3100 so severely that I had to have the formatter replaced. Twice. I think the presets are created using the Designjet Media Management SDK and I think this is probably what you need to do anything at all with them but information on SDK is hard to find.
