Can we change order with in any category (status, Severity etc)?

Suppose we have three severity level i.e. 1, 2 and 3 and within each we have 10 requests each.

Is there any way to define the priority of these 10 requests ? 

Can we change it by dragging and dropping from the Kanban Board?

example: in the image below, Under "Open", I want to change the order of incident #3 to  come above incident #2 to show that agent should work on #3 first.
