need DNS record added with underscore in record name for domainkeys

[dblaine21]

Hi, I use Google Apps as my mail server, and would like to use domainkeys (DKIM) for added security. This requires creating a TXT record in DNS (hosted by X10) that uses an underscore in the record name (google._domainkey). Cpanel doesn't allow me to add a name that has an underscore. Could someone please help me add this record? Thanks very much.

I can escalate this ticket, but I am unsure if an admin, as cPanel is very pickey and they might not even have the ability to do it from their side.
