Change column order & name from Datagrid properties window

When I have a datagrid with a LOT of columns (usually when wanting to make use of default excel export functionality), changing column order and names can be quite a pain in the a... apple. pain in the apple.

Anyway, if I were to be able to change the order and name of the columns in the Datagrid properties window (image below) that would be way easier. and awesome.

Seems like a quick win :)
