Numbers: custom sort order of a column
Caveat: I already know how to sort the table using rules for the columns, alpha-numeric ascending or descending. I already know how to drag rows into a custom order. What I need is to be able to custom sort a single column. For example, if the column has cells with data the following entries (red, yellow, green, blue) and I choose sort ascending, the column will be sorted to blue, green, red, yellow. But what if I want the entries to be sorted in a non-alphabetic order, say green, blue, yellow, red? I know I can number the entries with an index (1 green, 2 blue, 3 yellow, 4 red), but is there a way to custom sort without that?
