Here is a "simple" feature I have seen on other platforms which I find to be a real time saver...
It would be great to be able to see the average of the output columns in the builder. It's a quick and dirty way to gauge the results without having to dump the data into excel. Say you have generated a number of sets of different strategies (with different inputs/assumptions etc). The respective averages is often a first filter of where to go dig and where to not waste your time. See the attached screenshot.
Thanks.
