App purchased should carry over

Great app except I purchased these "in app purchases" as regular apps previously. If you had purchased the other apps prior to this app being developed there should be a way that they are carried over into this app to allow you to use the play list feature. Please do an update where this is a possible, Im sure other users would greatly appreciate having all previous purchases linked to this one app.
