How to add transformation "Labels to fields" in a alert rule?

I’m wondering if it’s possible to add a trasformation parameter inside an alert rules?

I add two screenshots to better understand what is going on. I simply want to use this “panel/query” inside an alert, but this is a very bad formatted SNMP metric, and the value is “1” instead of the temps, that are inside the labels. For the panel I used the Labels to fields transformation and I someway fixed it, but for the alert?
