How to add new value to FormSection in redux-form?

Question

redux

one.

const formValues = (state: ApplicationState) => getFormValues('valuationReport')(state); // форма (не имеет своего FormSection)

const formSelector = createSelector(
  formValues,
  (values: Object) => get(values, 'reporterCompany'), // создаем селектор для секции формы
);

2.

const mapDispatchToProps = {
  changeField: (field, value) => (dispatch) => {
    dispatch(change('valuationReport.reporterCompany', field, value)); // прокидываю ф-цию в пропсы компонента
  },
};

export const LienPageValuationReportController = compose(
  connect(
    mapStateToProps, mapDispatchToProps
  ),
  reduxForm({
    form: 'valuationReport',
    destroyOnUnmount: false,
  }),
)(LienPageValuationReportContainer);

How do I add my data here via the CHANGE method (now available in props) from the redux-form box?
The problem is that I don't know how to access the form...
When there was one FormSection (no nested ones), everything worked, now it doesn't.
