Wouldn't it just be easier to run iFly on your intial device (I'm assuming that's a tablet or desktop) and do your flight planning using it instead of using SkyVector? Then everything is backed up in the cloud (by iFly) and can easily be "sync'ed" onto (or shared to) all your devices, without all the manual effort you described.
I used to use SkyVector and I still do sometimes, but iFly is a lot more capable.
