A new undo button idea in edit base mode

Here is the solution for a big problem while editting our bases.While editting bases we misplqce our walls sometimes and sometimes they get stuck in those place where we can not find it for example:-they get behind the building where we can not find it and unfortunately we have to make our whole base again because of that 1 wall and it seems so silly and makes us so angry that after completing our whole base we misplace our 1 wall and we can't find so we have to make the base once again cuz it makes the weak point for our base.



So here is the solution:-

What can be done is a button can be made which undo our moves while placing our buildings so that if we placed our wall in a wrong place we can undo our move and send it back to inventory and it is better than remove button especially for walls but remove button is also important I am not saying replace it with undo button but plz. make a undo button in side of the remove all button.
