How do I pass specific information from one Knime loop iteration to the next

Hi everyone, I am running a chunk loop in Knime to categorize data in a table on a row by row basis. I would like a way to bring the past categorization information from the previous iteration and use it in the next. For example, for the second iteration of the loop, I want access to the categorization I made and stored in the first iteration. Can anyone help me with this problem?
