It may work that way with Gen 6-7, I'm not sure if it edits the saves in realtime or exports/edits/imports in one go. Either way, NDS .sav files from ROMs are NOT supported regardless, the program won't recognize "digital" installs of NDS games because they don't exist legitimately. Hell, the VC releases of Gen 1 and 2 ARE officially released and he still refuses to support those because "he doesn't want to buy them." So you see what I'm getting at? Anything not availble through official means IS NOT SUPPORTED. Period.
