• Replace button swaps the selected candidate with selected primary, making the candidate the new primary selection
• Remove button removes the selected candidate
• Update button updates the data fields selected in the primary data object's data listing with corresponding fields from the selected candidate's data listing
• Merge button updates the selected primary data object's data fields with the selected data fields in the selected candidate's data listing
