Multiple A Records

We have 2 ISP's with two different blocks of ip addresses from the respective ISPs.  Whe have some webservers published on IP's from one ISP.

What we want to do it set up "secondary A records" to point at the second ISP should the primary ISP fail.

Note that I'm not talking about load balancing or round robin.  I want the A record from the primary ISP to be used all the time, unless it's unreachable in which case the IP for the secondary ISP will be used.  I suppose it's similar to the priorities for MX Records.

Is there anyway of doing this from a DNS perspective>?
