[44net] AMRP DNS NS records?

I noticed that on AMPRNet portal DNS settings do not offer setting NS records for domains. Whz is that? I have full capable host and it can easily deal with DNS zone for domain I choose. Al I need is to be able to set NS record to point to my host. As it is not is too much hustle. First I have to manually maintain DNS and then, my host assumes that if it hosts domain then it hosts DNS zone too. Pedja YT9TP
