How does on put in a feature request?
It would be really nice if you could save a custom sort in calc that stays attached to the sheet. I have one that’s about 12 fields and it’s a pain to have to do it every time I open the spreadsheet.
Have you tryed, giving a name to that range in Menu/Data/Define range, before define the sort.
Then going to any place in data range or selecting in Menu/Data/Select range, use your saved options to sort Menu/Data/Sort.
