Unlink Several Objects Animation

Is there a way to unlink many objects with a single key? I tried using Alt in the Actions editor as it works for many other parameters but it doesn’t make all the objects single users. I think this should be fixed in 2.8 because it feels inconsistent. Clicking while holding ALT in any value will change all selected objects values. It should do the same when simply clicking on the animation users while holding ALT and clicking to make them single users.

I also tried using U but no menu pops up in 2.8

It seems that switching from the Keymap preset I had to Blender 2.7x the U works again. Anyone?
