Failover with only some sensors?

Hello,

i have one network in a city that i will monitor using PRTG. But: if the internet connection fails, notifications will be not delivered to me.

So, at one other location i could install a failover cluster (but in case of failover i won't monitor ALL sensors that the main location do) or i set up a free installation up to 10 sensors for only monitoring the internet connection.

What would you prefer? Is it possible to build a failover that only monitors some sensors at the backup place?

thanks in advice !
