Clustering: nominal to numerical and way back

I'm facing this problem. In cluster analysis, I have to convert nominal values to numerical, and that's pretty straightforward using the appropriate widget. But then I need the original values (in my case, shop names) in order to make the results understandable. Any suggestion? Thank you!

    I would create a data table with the numerical and nominal values and the use the "join" operator after the clustering analysis to add back the nominal values.
