Block Incoming International Calls/Text from Entire Country Code

I am attempting to block an entire country code from my phone. I am aware I could Silence Unknown Calls, but I prefer a better solution. The 3rd party call block apps (Truecaller, nomorobo, shouldianswer, robokiller, etc) are hamstrung by Apple. On my Pixel, I can easily block entire countries and/or international calls.

Apple needs a "Block International Call" toggle switch. Until then, I am in search of a better solution.
