This mod allows the /fill command to accept multiple arguments that handle how the blocks change [outline/hollow/destroy/keep/replace]
Examples:
/fill ~ ~ ~ ~ ~ ~ air replace gravel destroy
destroys only gravel as if it were broken by a player
/fill ~ ~ ~ ~ ~ ~ stone keep outline
place a hollow cube without replacing any existing blocks
/fill ~ ~ ~ ~ ~ ~ air replace #minecraft:base_stone_overworld outline destroy
breaks the borders of a cube made of overworld cave blocks
