Select an Address App pop-up notifications

We are using the Select an Address App. We only have one scenario for it, and that is to ensure every ticket goes from our default help@ address at our domain. Contact forms from external sources have to deliver to the subdomain.zendesk.com to circumnavigate SPF issues. 

Because we dont need to change the ‘send from’ address, we really do not need the pop-up box that comes up informing us of the change. This happens on every single open ticket one clicks into, no matter how many times you click into it, and even happens if that correct address is already set. Therefore the pop-up box feels very heavy handed and too frequent. We would love to surpess or turn off that pop-up notification altogether.
