[NTG-context] Repeat second-level registers within index

Hi, How do you prevent ConTeXt from hiding (collapsing?) duplicate level 2 index items? For example: \startitem 5 array \index{hedgehog+SECTION A}hedgehog \stopitem \startitem 7 army \index{herring+SECTION A}herring \stopitem \startitem 100 bloat \index{hippopotamuses+SECTION A}hippopotamuses \stopitem The text "SECTION A" will only appear once in the index, right after hedgehog. I would like it to appear once per index term, always. Such as: *H* hedgehog SECTION A 2 herring SECTION A 2 hippopotamuses SECTION A 2 For more details, see: http://tex.stackexchange.com/questions/134952/force-second-level-index-to-be... Kindest regards.
