Hammer with functions for 1.22

The hammer would have the function of changing blocks that had already been placed, for example: inverting stairs and slabs, and even leaving these blocks vertical, as we have been asking for for a long time. The hammer would be crafted with 5 minerals and two sticks, the wooden, stone, iron hammers, etc... could have this function or just those made of flint, And with just a hammer you could use the blacksmithing table.. This is my idea and since Minecraft is also a construction game it would give it an extra charm and it would also be iconic for players to use the hammer to build.
