Coloring for UNASSIGNED requests

Coloring for UNASSIGNED requests

Hello,
in MSP 11.1, on Requests screen, there is coloring scheme button for requests depending on request status.
It helps for quick differentiation of closed, opened, solved,..etc request statuses.
However, I would like to achieve that UNASSIGNED requests also have it's own color. I didn't saw this in coloring scheme settings. Is there a way to automatically color unassigned requests to some color, or have them "blinking" or...whatever just to stick out when you glance at ALL requests screen.

Thank you.
