Advanced Random Chest Fill Plugin

I finally have found a plugin that is similar to my Request! , for everyone that is interested too its called hyploot, Page: http://dev.bukkit.org/bukkit-plugins/hyploot/
Theres still one very important problem.
You have to define every chest manually..
I couldnt get this done, there are about 400 chests..

so still, heres my request:

Plugin category: Mechanics/Admin Tools

Version: 1.7.2 forge + flans +mcheli etc.

Suggested name: Advanced WE Chest-Fill

What I want: a config file where i can list the item ids, damage and their total amount. a command in association with World Edit where you can select a region and fill all chests in this region except redstone chests averagely and randomly with the config listed items. But to use it more wide it would be nice if you could set which chests are defined and which not and things like that. So i just implemented this at the example.

Example: selecting a map that includes 2 chests, add the ids + damage + total amount
Ideas for commands:
----------------------------------------------------------------------------------------------
#Config
----------------------------------------------------------------------------------------------
*something like this:*

"ItemSet-1"
- Type: 363
Damage: 0
Total Amount: 5
- Type: <Another Item ID>
Damage: <AnotherDamageRatio>
Total Amount: <AnotherTotalAmount>
----------------------------------------------------------------------------------------------
#Ingame
----------------------------------------------------------------------------------------------
#//wand + select region
/advfill define normal "<-normal chest=ID: 54" [only]
or
/advfill define trapped "<-trapped chest=ID: 146" [only]
or
/advfill define "<-normal chest=ID: 54 + trapped chest=ID: 146" [both]
and
/advfill undefine "<-to undefine all selection"
----------------------------------------------------------------------------------------------
#Next Command
----------------------------------------------------------------------------------------------
/advfill clone ItemSet-1 "<-clone filled" [e.g.: 5 in the first 5 in second chest]
/advfill average ItemSet-1 "<-averagely filled" [e.g.: 3 in the first 2 in second chest]
/advfill clear "<-clears items in the defined chests"

Ideas for permissions: advfill.define & advfill.set (default false) [Dont have much knowledge with permissions . ]

Do you guys know any plugin like this? Or can you guys script a plugin like this? I REALLY would appreciate it
