Tagging Tabs

[Sark]

My workflow includes me looking through a folder of photos and viewing each in fullscreen to access those I wish to keep, print etc. Once I've finished I have tabs for all my desired images.
It would be great if could you could tag all the images currently tabbed.
I know you can do this as you go, but a one click option for tagging all tabbed images would be very useful.
