Populate a column based on a query filter

Hi,

New to Appian!

I have a query filter rule:

a!queryEntity(
  entity: cons!PINBuddy_DSE_Wizard,
  query: a!query(
    logicalExpression: a!queryLogicalExpression(
      operator: "AND",
      filters: {
        a!queryFilter(
          field: "particpaitUpdateCutOffDate",
          operator: "<=",
          value: today()
        ),
        a!queryFilter(
          field: "paymentMethod",
          operator: "<>",
          value: null
        ),

      },
      ignoreFiltersWithEmptyValues: true
    ),
    pagingInfo: a!pagingInfo(
      startIndex: 1,
      batchSize: -1
    )
  ),
  fetchTotalCount: true
).data

Based on these filters, a list of records get generated, how do i write to a specific column, say "particpantNoteExtracted" to these records?

Hope my question is clear.

Thanks in advance

Neil
