Hi Community,
Could you help me in findin out how to put in a single column all the references that are scattered in several columns and that are sometimes repeated. In the image below I illustrate my case. What I would like to achieve is completing the colmn "Title 2" with the missing references that are in the other columns (Title 4, Title 5, etc) . The ides is to create a list with unique values as shown in the picture.

This post is actually a more complex case that the one already solved in:
