Alternatively, I'm not sure about this, but I think you could just add these extra labels in your alerting rules.
Labels added there are templated, and there are various template functions available, including reReplaceAll: https://prometheus.io/docs/prometheus/latest/configuration/template_reference/ However it would have to be repeated on every alerting rule where you wanted to do this sort of grouping.
