Hi--
The best source I have found is this:
http://www.country-files.../big-cty-02-march-2020/
It is what LOGic uses for individual callsign lookup for calls that do not match a prefix.
It has:
CQ1,CQ8,CR1,CR2,CR8,CS4,CS8,CT8,CU
So LOGic should be:
CU,CQ(18),CR(128),CS(48),CT8
Thanks for reporting this. I will fix it.
Tnx & 73,
