A button in blueprint interface that creates deconstruction planner that contains only items used in the blueprintSo with big blueprint (or small too ) you can easily create a deconstruction planner that touches only items used in that blueprint and not anything else.
This could be usefull mostly in heavily moded games, with a lot of aditional building where you have to trainsition from one build to another over time.
