Multiple printers, mulitple Pi's 1 web interface

I have 2 printers and 2 RPi 3b+ running octopi. They work fine. My question is how do I set up the web interface to use them both and monitor them both?

Thanks
Dave

You should change the hostname of one pi.
Connect via ssh (just power on one of the pis) and change the hostname with raspi-config

(scroll down to the "Change Raspberry Pi Hostname at Command Prompt" part)

Then you should be able to connect to one pi with http://octopi.local / http://octopi / http://IPofTHEpi and to the other one with the new hostname instead of octopi.
