We'd like to transit their CLID, but I really don't want to troll through my usr_preferences to pull 1000 CLID, and then identify which number they're sending and checking to see if it exists.

Then when the client sends us their CLID in the display name section of the From header, say 18007775566, we could check against the XXXX portion using a regex, and if it returns true, we accept the CLID and instruct the C4 to present the CLID. If not, we return a SIP error saying "Invalid CLID" or something like that.
