Pin blueprints in construction

We should be able to pin the base pieces that are in construction, so we can see the materials we need for that specific piece instead of the general materials. Say for example you built half of it but you still need some resources. Pinning it would show the mats we still need and not the ones we already put into it. Hovering over the “hologram” of the construction site and pressing a hotkey could pin and unpin the recipe. This would be specially useful when fixing that large story location.
