I have seen it but can no longer find it. When you receive a phone call, you scroll the window up & choose a reject call message that sends a message to the caller as to why you cannot answer. I want to add a message to that list so every time I get a call, I can select it instead of typing it out on each call. Where do I go to add those? I thought it was in the settings of the phone app but I no longer see it. Thanks.
