Has this feature been added yet? I know how to block text messages based on phone numbers, but that does not help. I keep getting the same SPAM from different phone numbers asking if I want to buy health insurance for 50% off. I could easily and quickly stop all of this SPAM by blocking one "phrase" as they all reference the same phone number in the body of the message. If this is not an option right now, may you PLEASE add it? This would be extremely helpful and make your app even better than it already is compared to other apps and a great way to market your app, especially since Samsung has removed this option from their built-in Messages app. Thank you.

I need this too!! Keep getting spam messages that include key phrases I could block on.

I need this too. Key Messages won't do it as they claim. And this feature was removed when I upgraded to Android 9.0
