verizonwireless Hotspot config issue

I use hotspot to connect my tablet to the web through my phone when I am out and about. With my last verizonwireless phone I could set the DHCP IP address and DNS server for my mobile hotspot clients (tablet). Unfortunately had to "upgrade". This new phone hotspot works, but the DNS server(s) it uses doesn't resolve addresses I need. The only thing I see under hotspot "advanced" is to set the Client (DHCP) start address. I need to change the DNS server the phones DHCP gives my tablet when it connects. How do I do that? Tried the support chat who didn't have an answer.
