Changing whats in the airdrops?

Is there a plugin that anyone uses to change the items in the airdrops? A player just picked up 8 quarrys and 8 survey charges in a airdrop, theres also AK's and Custom SMG's spawning in them like nothing.

Thanks for the help in advance!

EDIT: Heres a screenshot of one. This one might be regular but theres really OP ones at times. http://prntscr.com/7lrddl

 

You might want to look into the plugin "BetterLoot"
Here is the mod's link: http://oxidemod.org/plugins/betterloot.828/

EDIT: This plugin does not modify airdrop drop tables.

 

This helps with airdrops? I thought it was only barrels and crates.

 

You are completely right TweetPvP, my mistake. I forget what plugin I used to alter the airdrop drop table.

 

Please look for it? Ive looked on oxide. Sorry but I really need this to balance out my airdrops.
