Removing duplicates from lookup fields

Is there a way to set up a lookup field without duplicates? I asked this here and I just noticed that the response didn’t fully solve the issue: The rollup formula ARRAYUNIQUE(values) still includes duplicates.

I’m not 100% sure if this will work, but you may want to try this formula to see if it works for you:

ARRAYUNIQUE(ARRAYFLATTEN(values))

Hmm this doesn’t do the trick. Any other suggestions?

Add a formula field containing ARRAYUNIQUE({Purpose (from Interventions}). This should work.
