where is option for text message reminder for note 5 - option 2 or 5 min interval ?

[AC Question]

it was in note 4 and s6 but i dont see it on note 5 - i see it in the alerts message options but not in the regular message options. i hate that-- it notifications my once of the text message and if not in same room the phone will light up in couple minutes later but now sound to let me know a message was sent and waiting for me to read it.. i dont want to change to handcent or anyother message app because i change themes often and like that... can anyone help me with this?
