@Dr Herbie: I wrote dragnstore which is an application that ticks every single box that you have complained about. You can also backup your phones to the same account.
Give it a try, and if you like it, I will "cough cough" sort out something for you. You can get a free 5 gig month trial.
If you don't like the design blame the design agency as I did what they wanted, but the application works.
