How to Write Number Patterns in Different Columns for Campaigns in SmartLead?

Does anyone know get Clay to write number patterns in in the different columns? Im trying to make it say 1,2,3,1,2,3,1,2,3 all the way down as I want the different numbers to be different campaigns to test(dont think i can differentiate it via normal way as the leads have the same results/personalization but just different copies in smartlead). I want the numbers as an easy way to tell the smartlead integration to know which rows/leads that go in different campaigns. So its equally split into the 3 different campaigns
