if they want to safeguard data integrity that is fine. But then they need to be consistent with this implementation. Specifically they should not provide check boxes after import showing all the forms they found for that account. By providing check boxes, they are creating an illusion that you can bypass import of a form by unchecking the box (thereby preserving what you imported before). if they want to stick with current implementation, then they should just list all the forms they found for that particular user/account without checkboxes and then let the user know that all these forms (accounts) will be overwritten
