Scenario: you are wearing a few BOM stuff on your face, including BOM head skin, each in their right stacking order, which allows your face skin to appear blending seamlessly with your body skin. And now you need to replace your head skin with the browless version. You tipically will detach the face skin with brows and add the face skin without brows, but this new attachment gets baked on top of everything else. The only way right now to fix this is to sort the bom stuff in appearance edit and save a new copy of your outfit wich is cumbersome when just trying new applier eyebrows, for example.
Idea: So I propose to have a right click option for bom stuff in inventory called "BOM Replace Temp" that allow us to just replace that bom item with a new one keeping its stacking order in the baking pile so it does not hide stuff like neck blender, hairbase and such and we can just focus on trying new stuff without having to sort and save temporary outfits.
