Dividing a Master List for Targeted Campaign Enrichment

Anyone know if there's a way to push only a certain number of columns to a new table? IE - I have a Master List. I want to enrich all my leads via that master list. I have 6 campaigns I want to test from that master list. I would like to divide that master list by 6 and push them into the correct campaign's list for further enriching & so I can easily export later. Is there a way to do this or do I have to export the master list first -> divide it up -> import into each campaigns list
