How to Make Imported CSV Lists Visible for Company Search Exclusions

Hello team, Could you please advise me? I wanted to create a new search (with search company table) excluding certain companies beind listed in my other tables (which were imported by CSV) I imported my list with companies to be excluded by CSV But when I create a new company search this list isn't visible on exclude section I can only see the one list (which was created by search company table) - it is visible, but not the other that were imported by CSV file import My question is: How to make a custom imported list (imported by csv) to be visible under exclude section of "Search company table"? Many thanks in advance!
