Hi
I've been playing around with the interface tools and the select tool and can't get something working, which I imagine is possible but would like some help/input into getting a solution.
Problem:
For different input files (but each file would broadly have similar data in) I need to rename certain fields so they will pass through to a Tableau dashboard. As each input file may be in a different language or field name headings may vary slightly and/or the order of the fields may be different per client, I need a way to update the way the select tool is working through a user interface.
An example of the current select tool set up is below:

What I want the solution to be able to do:
What I would like to have is a set of drop down boxes using the interface tools, which enable the user to pick the fields in the input file and map these to the corresponding required fields for the Tableau input.
A mock up would look like this (assuming the translation to French works):

So any pointers or help from the Community would be greatly appreciated.
