hotspot & Userman Login with automatic Mac Binding

I would like to know if i can achive this configuration on Microtik.

  1. I have setup Hotspot and Userman
  2. Once a user logs in with hotspot popup screen (Username and Password), i would like Mikrotik to automatically add device mac address to ip binding so the user will not have to login to the device again till his or her time is up.
  3. Once their time is up it will logout the user and delete Mac address from Ip Binding.

Can anyone help me with this config?
