In Fallout 4 and 76, you can tag items to look for in the world, even items composed of the items(s) you tagged. If Witcher 3 could do the same, it would work like this: if you look for resin or twine, you tag them in your inventory or crafting screen; then anything in the world that is composed of resin or twine, such as ropes, will be tagged as well, so that you only scavenge what you need without burdening yourself with items you don't need. So could this be done in Witcher 3, with some mods perhaps?
