You set up a helper column that concatenates the adjacent cells. A UNIQUE
function will not help there. Or I misunderstood.

How is that in any way related to a UNIQUE function?

Note that to work correctly a UNIQUE function would have to output an array of
rows. After being entered the first time the output array size would be fixed
to the then number of unique values. If data was added to the original range,
the range the UNIQUE function occupies / outputs to would *not* be extended, so
would be pretty much useless then and would have to be re-entered, deleting the
original range first. The situation is not much different from the
filter-unique-to functionality, on the opposite, it would be even more
cumbersome.
