New Allow and Deny Block Mix With Toggles

We all know the deny and allow blocks, which are very useful map-making tools, but there is one problem. For people that build maps or mini games, like bedwars, there is a problem, you need to let players build, but not break blocks. this is a massive problem for people that want to build bedwars. I suggest a new block, only obtained using commands and must be operator & in creative mode. It would work as a mix of a allow and a deny, but with a twist. It would feature 2 toggles, Allow Build and Allow Break. They are quite self-explanatory. Allow build lets plays build and allow break lets players break blocks. They would also have a toggle that lets you change them from effecting above or below the blocks.
