USability: Save button in Rules Engine Field Mappings is confusing

When adding multiple Objects to Data Load Configuration, the Save button is a bit confusing:

To reproduce:

1) Add a few Objects
2) For each object, select the fields you would like to grant access
3) Click the Save button

Because there is no feedback indicating *what* was saved, as a user, I would expect that all Object field permissions would be saved.

Instead, only the Object that you're currently selecting will have the corresponding fields saved. I suggest:

1) Changing objects will prompt the user to Save Changes or cancel OR
2) Save all forms for the Objects selected by the User when the user clicks the Save button. 

Either way, the Save button should indicate what objects were saved / updated.
