Is it possible to concatenate the values of several dffs into one dff

Summary:

Our client has a requirement to concatenate the values of 3 DFFs (Free-text) into one dff. For example:

Field 1: 123

Field 2: ABC

Field 3: No

Field 4: 123-ABC-No

I am thinking it is possible by setting up the query via table valueset. But we are not sure how to go about it. Would appreciate if someone can provide insights if this is possible and if yes, what are the possible ways to do it? Would also appreciate if you can share any documentation. Thank you!
