Adding a second Oppo 105D player to your network

Oppo help!  Can anyone explain how to add and name a second Oppo 105D player to my network? I am currently having to type in each individual players IP address on my iPad to use it.  When in the app, one player appears on the Player Screen, and there should be a way to add an additional player I think??  I am using the Oppo Media Control ap on the iPad to stream Tidal.
