Categories in midnam files?

In Ardour 4.2 I can select a patch from my Roland JV-1010 midi device. That’s great but you first have to select a bank and then the patch. Is it possible to divide the patches into categories like “Brass”, “Piano”, “Bass”? I looked at the midnam file of my device but I could not figure out how to do it. I guess it is not possible due to the nature of a midnam file. Is it?
