DR14 - Clip Usage indicator

Hello,
I would like to know if is there an option to mark clips which are already used on timeline, like in Premiere Pro which shows blue icon on a thumbnail?

I've found that option in List View, but I need it in thumbnail view.

I did not find a direct solution, did you?

I use a workaround. I sort all the project clips by usage, and flag the unused ones. And flags do show in thumbnail view. But of course I have to do that manualy to update the info.

If the "usage" column would work as described in the manual, and show "x" if clip is not used, we could use "Filter by Usage" to show only x-ed clips.
