Using (spare) HomeBase as doorbell gong

Does anyone know if it’s possible to use (a spare) HomeBase 2 as Doorbell gong? I purchased a HomeBase 2 with a Doorbell camera, but I decided to upgrade to HomeBase 3 with some extra S330 cams. The problem is, I barely hear the doorbell from my HomeBase 3. It’s placed inside a closet. So instead of buying a dongle/gong, I want to use the spare HomeBase2 and set that one up in the living room.
