PreviousLevel in a Lambda

[izenn]

I'm trying to write an alert where there is Critical, Warning, Info and OK. I'm running into an issue where the cpu usage will occasionally go between ok and info and i do not want to be alerted if that happens, but i do if it goes from warning down to info. It looks like there might be a way to get PreviousLevel (i've seen it here: #2668 and #2715 (where there looks to be "previousLevel" available.

I'm not seeing that in my data:
{"Name":"","TaskName":"test-task","Group":"host=xxxxxx","Tags":{"host":"xxxxxx"},"ServerInfo":{"Hostname":"localhost","ClusterID":"xxxxxx","ServerID":"xxxxxx"},"ID":":host=xxxxxx","Fields":{"cpulist":"cpu0","status":"CHECK","timeframe":"30 minutes","used":0.16255418860727153},"Level":"INFO","Time":"2023-03-24T17:30:59.663545193-05:00","Duration":10797827655742,"Message":":host=xxxxxx is INFO"}

is there a way to get previous level when using a batch query so i can put some extra logic in my info alert?
