Adding new items ID to looter [Help Wanted]

[Macho]

No item match the loot id name, some like Mastermind shield on OTS has id of chain helmet for example. I am adding it as chain chain helemet and it loot properly but most of items ID arent on list so i wanted to add those IDs manually, though i can do i through NewItems.txt but no effect.

Please is there anyway to add those item IDs to looter list on my own?
