YAML Anchors calling other YAML Anchors

I have two environments I deploy to, and two types of deployment I do to each. The deployments are almost identical except for their first step.

I've moved most of the steps to YAML anchors, but I end up with 4 pipeline definitions, each with the same number of steps. It'd be good if I could create a definition that chained other anchor steps. That way I could create an anchor that was steps 2-5, and then my pipelines would simply be "Run Step 1, then the anchor that does steps 2-5"
