Adding new items ID to looter [Help Wanted]

[Macho]

Hello,
Please be so kind and tell me if there is any possibility to add New items IDs to looter, tried adding some in NewItems.txt but it didnt work. Any other solution?
I am playing on OTS at this moment so most of IDs are changed or missing.

Also is there any option to add custom corpse IDs?

Thanks in advance for fast reply.
