No there isn’t a feature like this, and yes some folk have indeed suggested it.
Personally, I’m in two minds. I certainly don’t enjoy rummaging through every crate, but then I quite like the fact that there’s just lots of stuff in the world that a Very Important Adventurer like me isn’t going to bother with, and once cured of the pack rat tendencies I’d developed in other games I decided that I found it more immersive that there are many containers and much junk that you’re just not meant to look through or pick up, any more than you’d go through every container or pick up every item in the real world. Now I usually just loot fancier looking containers or other stuff that looks more interesting, or if I’m feeling a bit poor or low on potions I’ll be a bit more thorough and enjoy occasionally finding a surprise good item.
It actually felt a bit of an epiphany when I realised I could just ignore stuff, and I feel that would be cheapened by making looting easier. But I’m not so mean as to object to the function being added if that’s what most folk prefer.
