selecting multiple "visibility-unselectable" objects in outliner should make them all "selectable" again with "alt" key

sometimes i make objects in Visibility "unselectable" like "freezing" in 3dsmax, that they cannot be selected in the 3d viewport.

i do this with the "alt" key.

this should be possible to make it the same way back!

means selecting 50 objects in outliner and with "alt" making all "selectable" again

thanks!
