Event Orchestration how transform content once before delivering to alternate Services

With original Global Ruleset functionality, I could adapt content from a certain monitoring tool, transforming its varying severity levels into PagerDuty standard levels. But to conditionally deliver a transformed alert to one of several Services – based on a certain field filter indicating Prod vs NonProd, for example – I had to basically duplicate the original collection of severity-setting rules and combine them with that additional field filter.
With Event Orchestration, is there a way to do this kind of “source” adaptation once and feed resulting alert to logic that decides route to Service? Avoiding duplication of transform rules.
