So far you set each app to do that. Yes there may be a mount2sd piece of advice out there but I found most folk imploded trying it.
So again, in short, change the app to do what you want. If the app is that bad, change apps. You've rooted so you are in full control.
I have a rooted phone. Is their an app or program that well let me set my default storage to my external SD so that pictures and everything i install are automatically stored to my SD? I am almost out of internal space and can no longer install apps or save pictures.
