The requested feature is available in neutron APi from long ago. You can use all things through CLI for neutron (neutron CLI or openstack CLI).
The reporter seems to request a network related feature to horizon. Horizon is a GUI project, so as horizon we only handle GUI side. As Horizon, we can add a menu like "Add IP" or "Remove IP" to the port table (but it is a minor feature and can be low-hanging-fruit)
