Question about custom domains

[epicman212]

My main domain has a bunch of DNS records under my default nameserver. I am wondering if I can host a Helio service under any subdomains without having to change my nameservers. Thanks in advance!

If you don't want to switch your nameservers, you can create an A/AAAA record to the IP address of the HelioHost server your account is on (which can be found in Plesk).
