How to import DNS records previously exported to CSV back into Server 2003?

I have previously exported a lot of DNS records from a DNS server on Windows Server 2003. Now I wish to import those records back into my DNS forward lookup zone. I however cannot find any menu within the MMC that allows me to do that. I am wondering if there is a way for me to import those records without having to enter them manually (there are nearly 100 records involved).

Thanks very much!
