[processor/metricstransform] is it possible to combine multiple data points?

[alolage-devrev]

Is it possible to use metricstransform processor to downsample metric data points? If yes, can someone provide a working sample processor config?

for eg. I have 2 service instances serving /hello endpoint and pushing metrics to Otel as gateway.

can above be converted into below in processor pipeline?
