Move selected row to bottom or last row of datagrid WPF C#

So I'm currently doing an automated IQ exam for our HR department. I'm using C# as my P-language and WPF as app foundation. My questions are stored on a mysql database and binded on a datagrid.

My question is, is there a way for me to move a row to the last row? The idea is, when an examiner skips a question, that question goes to the last row of the datagrid. Thanks in advance!

Edit: I've added a picture to explain my idea. Hope it helps!
