Creating Company Table Data Column in Existing Clay Tables

Hi everyone, I desperately look for help about this issue : When I create a new table from source "Find People" using a "Clay table of companies" I can see a very useful column "Company Table Data" created automatically that retrieves information from the table selected in "Clay table of companies" (cf. screenshot) When importing the source in an existing table, this column is not created. I would like to create it manually in my existing table. I searched everywhere in the available enrichments and the support section but I did not find anything similar to this "lookup Company". I really hope it's possible because my existing table is pretty complicated, it would be very painful to reproduce it in a new table with the "Company Table Data" already present. Could you please help me to achieve that if it's possible ? Thank you a lot and have a nice day !
