Effective Ways to Separate Contacts by Company in Clay Table

Does anyone know the most effective way to separate multiple people that work at the same company in a clay table? I want to do this to have these people if different campaigns. Currently I have a Clay list on where every row i a unique contact but there can be multiple rows / contacts associated to the same company. I used to export the sheet and do this Google sheets but I wonder if there is a more effective way to do it in Clay 🙂
