AT:

• I can immediately define an external report on the add report modal
• In the add report modal when I click on "Add external Source", the modal is expanding with the modal with the information to add the external report
• While the modal is expanded the report select is disabled
• When I click on "Add external Source" again, the modal is collapsed and the report select is enabled again

Context:
Feedback from Felix: If a user wants to go back from the external source modal he needs to first close the modal and the open up the add report modal again. That feels clumsy and counter intuitive.
