Manually choose to route traffic to a failover pool

I am using the load balancing service and have set up a failover server. For site maintenance purposes, I’d like to push traffic from my IP address to the failover server, conduct the maintenance, and then resume normal load balancing operations. I know I can temporarily reconfigure the pools to push all traffic to the failover server but I’d rather not do that while maintaining the failover server. Does anyone have a tip that would allow me to do this?
