Ring Alarm base station silent option

We need to be able to put the base station in silent mode. In order to prevent smash and grab you do not want anyone to know where the base station is located. With external sirens you can still make noise and not reveal the base location. And, some people may want a silent alarm. We have the option to set the volume for alerts, but no way to turn off the base siren. Makes no sense not to have the option.
