Thanks for the explanation - as you know I do not have pro+

leaving aside soft group, if an item is locked you cannot right click and so as stated you would need to use the P&L gallery

traditionally what I do is use the global unlock, use locate to find the item in the gallery, and then relock globally before proceeding any further [I have even been known to do this on a copy file where is was super-critical nothing went pear-shaped]
