A wall is a wall and it needs to be repaired.

[Gerpus]

Let's imagine a situation where I built a beautiful house or wall, and it was destroyed or broken by a Creeper, then I will need to manually restore it, my idea is to help us in survival be able to select a building and assign it, for example, a tag (wall, house, building, farm...) and if suddenly this building breaks, then the builders from the mod could fix it.

You can already do this using the scan tool.

You may need to scan each wall individually, though, as if you scan the whole building and then later tell them to rebuild it, they'll rebuild it exactly as it was (including removing extra blocks you placed later).
