Automating "Change Multiple Sites' IP Addresses" using SSH/bash script, possible?

I am using "Change Multiple Sites' IP Addresses" to change the IP address assignment of all the sites under ResellerA including ResellerA's website

If there are roughly 100 accounts, this appears to be a tedious task. Is there a way to automate this using SSH and perhaps writing a bash script? If there is, what is the "script" that should be called by the bash script so it will automate the process?
