Frequency of Disclaimer Only Page

I am trying out FortiWifi for my Organization. I am setting up a public guest SSID. I will need to have a disclaimer page setup that that guests will be redirected to when connecting. Is there a way to change how often a user is redirected to the Disclaimer Only Page? With our current wifi solution guest only get redirected to the disclaimer page every 30 days. Our current wifi system was setup this way because employee's complained about having to go through the disclaimer page every time they return to the office with their personal devices.
