Can I block entire area codes?

[CoreZero]

With the increase of spam calls I would like to be able to block block an entire area code, or be able to block any calls that are not in my contacts. I would prefer the former but would take either one! I got through settings and didn't see either of those. Feature request if not there. Thanks!

You can block all numbers that aren't contacts, they will automatically go to voicemail.

Open phone app, tap the 3 dots, go to settings, block numbers, turn on Block calls from unknown numbers.

In most cases, the Asterisk (*) is a wildcard character. Is it possible that the asterisk can be used for the seven digits after an area code to block all numbers in the area code?
