Percentage_diff_abs on multiple series

I have a query (from a Dataset datasource) that returns multiple series.
I’m fairly certain that in an older version of grafana I was able to get the percentage_diff_abs per series, but I’m learning that classic conditions are uni_dimentional.
I can’t exactly remember how I had done it before, but I have historic alerts in slack showing that I was able to.

In any event, is there a way using the current expression types to take the multiple series that are output by the query and alert on a percentage_diff_abs for each one?
