How to add the Half Day Option field into the Absence Planning page for display?

May I know how to add the Half Day Option field (i.e. First Half/Second Half) into the Absence Planning page for display?

Checked in Visual Builder, this field is not available in the Absence Request Detail Component or any Business Rules. Is there any method to bring in this field (ANC_PER_ABS_ENTRIES.START_DT_DUR_PREF_CD & ANC_PER_ABS_ENTRIES.END_DT_DUR_PREF_CD) into the Absence Planning page, so that managers can refer to them before approval?

Thanks!
