Proper way to park a domain for a sub account?

Hi,

I have a reseller account, so I do not have full control over the server.

I have a client that needs to park about 30 domain names.
His registrar will not let him change nameservers to a server that is not hosting the sites, and cpanel will not let him park the domains while the nameservers are pointing to another server.

So what can I do?

I logged into whm and parked a domain for him, then he changed the nameservers, but from his cpanel account he did not have control of the parked domain and then I could not find it anymore...I had to get the server admin to take care of it.

Well now He wants about 30 done, so is there a proper way to do this?

 

Thanks

I sent them the request, hope they do it!

Thanks for the help

 

They refused to do it, they said it is a security violation?

Is this true?
