Set ringtone for specific Caller ID NOT phone number ?

[Android Central Question]

Is there a way to set a specific ringtone for a Caller ID ?
We have a service that flags spam phone calls with the Caller ID 'Possible Scam'.

Obviously we don't know every number that could be flagged this way and don't really want to add hundreds of numbers to a 'contact'.

So, if possible, we'd like to simply set a specific ringtone (or set to no ring), anything with the Caller ID of 'Possible Scam'.

No, this isn't possible. To block numbers there has to be a contact for the number, not Caller ID.
