[NTG-context] Sorting registers method for "uppercase like lowercase, diacritics ignored"

Dear list, In the wiki page https://wiki.contextgarden.net/Registers it is said that: - There’s no preset for the combination "uppercase like lowercase, diacritics ignored", try "zm,pm,zc,zm,uc". Well, I tried all possible permutations thereof, and also the predefined methods, and none gives what my editor wants, which is just "uppercase like lowercase, diacritics ignored". See MWE attached. Please, would somebody help me achieve the desired result? TIA ConTeXt version: ConTeXt Process Management 1.02 current version: 2019.01.19 12:06 Marcus Vinicius
