I own two KPA units, a powered rack and an unpowered toaster. I use the rack for the vast majority of my gigs so it generally lives in the band's gear truck, which is why I bought the toaster, so I'd always have one here at home with me as well for infrequent fly dates, pick up gigs, etc.
I started with the home unit by just restoring from a backup I'd made from the powered rack (my main Kemper). What I'd like is the ability to just export select rigs, patches, etc that I've worked on on my home Kemper to a thumb drive, then when I get to my gig Kemper, just load those specific rigs/patches/slots/newperformances/ etc. I don't have a laptop, just my trusty iMac at home, so loading individual rigs that way isn't an option when the main KPA isn't here at home.
The way it is now the only way I've found to do it is to do a full backup and restore cycle - this is a bit clumsy as a solution and seems like overkill to overwrite the entire memory when just a small change or a bunch of small changes. It would be a lot more user friendly to have a soft button to import rigs, select which slot in which performance or which performance number to create/import to.
