Messaging within Secure Folder

I have a new Note 7 and have setup contacts within Secure Folder. When I click on message (text) or phone for that matter, Secure Folder puts a message at the bottom that says "you are using this application outside secure folder" and then it shows the text outside secure folder in my texts and if that person responds it shows up there too. How can I text WITHIN secure folder? When I try to "add" inside Secure Folder, it only allows you to add "apps" that you have downloaded into your phone from the Play Store (not the text messaging that comes as part of the phone. I also install My Knox for Android from the Play Store and same situation. Seems like I should find a way to text WITHIN secure folder...
