client group resellers

[WIS hosting]

Hello,

 

I wish to create a client group for my resellers and then discount them on the purchase of domainnames.

 

I already contacted support, but this doesn't seem to be possible. Only to discount them on ALL invoices. But I want them to pay the normal amount for hostingpackages. Only discount on domainnames is necessary. I don't want to hand out a promotional code.

 

Another question:

I want my resellers to change the nameservers of the domains. All other users are not allowed to change nameservers in the productdetails window.

 

I thought about doing this with a if... else statement. But my programming knowlegde is too less.

Maybe somebody knows what string to use (in full?).

 

Thanks!
