set-to-flag node will 'flip or transpose' your single column/field bin with 9 category values into 9 fields, each with a nominal yes/no default value. You can instead use 1/0 or after the yes/no nominal values use a filler node to replace the 'yes' with any value you chose, including a value of another field. If you replace one value with another make sure they are noth the same data type (cannot replace 0 or 1 with text)
