Sync with 2 iTunes libraries?

[mrbarker]

Hey all,

I have a computer at home with music files and a computer at work that I keep movie files on. When I add files from one my phone wipes the files from the other. Is there an app that will allow me to sync from both libraries without wiping the files from the other computer? I am signed in to iTunes on both machines with the same account
