Several Members have expressed an interest in an app for this sort of thing but I'm afraid it's simply not possible. The apps in the iPad are 'sandboxed' and so it's not possible for one app to control another app, which is what would be required here. Apple deliberately did this to avoid the possibility of an iPad ever getting a virus - since any malevalent code downloaded to your iPad would be unable to affect any other aspect of the iPad's operation. Downside is that what you're trying to do is just not possible.
