Brilliant! Please send in an employment application right now.
I guess I was proposing that the Kobo desktop app do it because, well, a PC or even a Mac is a lot more robust and faster than our shiny gadgets.
Really, the app should have a lot of the same management functions as Calibre (Kovid Goyal, please send in a proposal to Kobo soonest), and leave the Kobo to concentrate on displaying books nicely. Which it does...once it figures out how to load a bunch of books without crashing.
