How can we improve WHMCS?

I'd like to propose addon to whoisservers.php
I'm from Serbia and we use .RS ccTLD and IDN designated for two-letter country code .??? (https://www.rnids.rs/en/domains/national-domains).
I'm very happy that you already added our ccTLD .RS to whoisservers.php (line 418-422) and I would like to ask you to do the same with IDN .СРБ. code are the same:
