ThinOS 10 WMS 5.1 on-premises DNS question

Have just resent started using WMS, we are currently phasing out the INI FTP solution, and transitioning to ThinOS10.

Have set up DHCP option tags, and thin clients register successfully to WMS.

What i want is the thin clients registered in DNS by their Terminal Name. I believe this is because they don't have AD verification, but not certain. I have limited DNS knowledge, and need to know what to request exactly. 

The goal is to be able to remote into thin clients using Terminal Name for support. I'm sure someone already has a solution for this. Any help is appreciated.
