[Check_mk (english)] Check IPMI Sensors via Freeipmi

I have set up the Check IPMI Sensors via Freeipmi special agent datasource program. It discovers services that can be monitored, but doesn’t monitor any of them by default. I must select individual services to monitor via WATO. How can I tell Check_MK to monitor all the IPMI sensors without going through each host definition and selecting them? I would rather all sensors be automatically selected for monitoring.
