Formula or SDK-based text field autocomplete

In text columns on tables there’s an option to enable suggestions based on other values in that column. This autocomplete is very helpful, however it would be awesome to allow makers or developers to control what these values are programmatically.

I would imagine that the UX could mirror the actions selection UX, where after toggling the ‘suggestions’ option there would be a selection input with options including ‘based on other values in this column’ and ‘based on a formula.’ This would enable custom autocomplete suggestions, some input validation, or (my specific need) autocomplete based on an external API via custom functions.

Alternatively, exposing this capability via a parameter in the makeColumn method within the SDK would also be helpful. You could just specify which function to run whenever the user changes their input.
