Once the outputs are set up it is impossible to see which region corresponds to which History output in the results. (Although the name should be explicit, I agree).
I do not think that a reworking feature is necessary. What about having a highlight of the region or the availability to see which output region is selected?
Thank you.
However, the outputs created in the results section are not highlighted anymore ; Only the ones previsouly created (before the calculation of the results).
