How can I join 3 text fields into one field?

Hi guys can you help me with this:

I need to join 3 text fields and the result is the same as a text field that does not repeat the information contained in each of the fields, For example: in the image I have 3 city fields, the city can be repeated in each of them and I want to unite the cities in a single field

Can you join these fields at a dataset level? Or need to be able to do this in the analysis?

I need can do it in the analysis

Currently the feature for combining fields is not available in the Analysis. We will add this request in our backlog. Thank you!
