[Feature request]: Parameter to indicate to a Multi-Select column to add only new values

[ronaldulate]

Suggestion

It is possible to add a parameter to indicate to a column or to all multi-select columns in general whether to add new values and not replace those that already had. For example, I have a multi-select column with categories and for an existing record that already has the categories 'planned, home', when I want to update that existing row "merge" with the label next, it replaces 'planned, home' with 'next' and what I was looking for was 'planned, home, next'.
