Brand doesn’t have 2 separate fields for the first and last name. Brand is the 1 field that sorts information by the first word that you have there. We can implement you sort by the second word for the brand elements and widgets by some minor customization if you would not mind to give us 5 stars rating because additional customization is not included into basic support. We need your FTP access.
If you want to add sort by brand option for the Products element it requires more additional customization and you can submit the customization request here.
