I'm familiar with the [`UNIQUE`][1] function in Google Sheets and how it works on rows (see Examples 1 & 2 below). 

Is there a function in Google Sheets that operates similarly on columns?

In Example 3 below, `UNIQUE` behaves as expected by treating this as a single unique row.

I've worked around this by using `TRANSPOSE(UNIQUE(TRANSPOSE()))` (see Example 4), however would like to know whether there's a built-in solution.
