link custom metric event to entity

[calfanonerey]

Hello everyone. We have metrics we're sending over to dynatrace and have metric events set up for them. Without using the new davis anomaly detector is there a way to link these metric events to an entity id? I tried using dt.source.entity in the metric event but it didn't link it to the entity here's the impacted entity from the problem card. I want it to be tied to that application ID

thanks!
