Make nslookup use specific interface

On my computer I have two network cards. Both are using different Internet Providers service. Both Internet service provider have different DNS server and their IP address are known to me. I want to make sure when nslookup sends queries, it passes through exactly by specified interface. Something like: ping -I eth1 google.com nslookup -I eth1 google.com is possible by any way, I know there is no -I option, I even don't want it to be specific in that way only. How do I do it?
