Display in 2D bow view that vial is taken out of freezer

When a vial is taken out of the freezer, that is not readily visible in the box view. You first need to click on the vial, and then you can see in the window on the right that sample was taken out of the freezer. However, it would be great if some flag could be placed on top of the icon or the grey out the icon, to show that the vial is not currently available.
