With the update to 2.02 I can see there are options to show missing tags for Aric's mod but I do not see any selection options to add the tags to images.
That is the next planned feature, the option to connect images or move them between Portraits, Bodies, Naked, and Pregnant
Added in 2.10
It's not pretty, but it works.
Click the Fuse/Separate checkbox, then click anywhere on the main list. The new features will become visible.
