wpa_supplicant: How to switch between different networks without disabling all others

I'd like to know if it's possible -- I hope and guess it is -- to switch between different networks in wpa_cli without using select_network, as this disables all other networks. Thing is, say I have n networks to connect to and stored in my wpa_supplicant.conf. For whatever reason, I want to switch from network 1 to 2. Right now I'm using select_network, which disables all the other networks 1, 3, ..., n. This means that if network 2 crashes for some reason, wpa_supplicant won't automatically connect to a different available network. I'd like to avoid that by finding a method to switch between networks without using select_network. Any idea how to do that?
