Is it possible to make another drop depend on what you use?

For example :
IronOre:
block: "IRON_ORE"
drops:
CobblestoneExplosion:
item: "COBBLESTONE:0"
chance: 100
require: EXPLODE or CREEPER //environment effect
Rock:
item: "SNOW_BALL:0"
chance: 30
require: HAND //either holding blocks or not
IronOre:
item: "IRON_ORE:0"
chance: 100
require: tool_pickaxe //any pickaxe
IronIngot:
item: "IRON_INGOT:0"
chance: 100
require: "DIAMOND_PICKAXE" //specific item (with meta support?)
type: block
append: false

"require:" is a command which items/blocks they can use in order to get the drop.
It can use any items, blocks and event environment effect.
If it's not using "require:", it can be earned in any way.

Well, if "require:" sounds silly, you can change it. I'm not the smart enough to think one.

Mini request, can you make decimal number for percentage?

Forgot to mention, this also can be done on entity (because sheep not dropping cooked beef when burnt to death)
