L2J Server

Hello, I'm new on this forum and I got a question. Couldn't find any more suitable section to post it, though. In the server I'm playing, we want to set All raid drops to x5, except certain grand boss drops (meaning the jewels). Is it possible to specifically change the drop rate of those? Because game balance would be lost if they drop jewels x5, while other drops do not play major role in our server.

rates.properties, config by the name of "rateDropItemsById" or smth like that.

Thanks for your fast answer.
