Let us know how we can make Jedox even better!
Thanks for the idea. This feature has been evaluated by us and we will not implement at this time. You can, however, use the new Subsets in Rules feature (from 20.3 onward). This enables you to to Averages, Medians, Max, Min, Count and other array style functions in rules. See the What's New 2020.3 or .4 for full examples of this.
