Combining more than two tools (when crafting to increase durability)

Currently, you can only combine a maximum of two (of the same) tools if you wish to combine their durability. (For example, you can put two low durability pickaxes to get a single pickaxe with greater durability). If you want to combine more than two tools, you can only combine two at a time and must repeat the process. Being able to combine more than two tools at once (e.g. up to 9 with a crafting table) should be easy to implement and it would increase QoL when crafting.
