Thanks for asking question! For Static web app we cannot bind our own certificates like as in Basic App Service. Also, the best way to share your feedback would be to create a User Voice feedback item and upvote it. The product group monitors this site for feedback. This is the best way to ensure you are heard and you may receive a response depending on how much they information they can currently share.
