Is there an new vegas additemmenu mod?
What does an additem menu mod do:
It adds an specific item called an "additemmenu" to your inventory. It scans all the IDs of items in the vanilla game, DLC, and mods and lists their ESPs via a menu once you type in what you're looking for.
AdditemMenu (Clicked) > Menu pops up to type in > Types "renamon" > Shows the ProjectRenamon.ESP file to click on > Clicks on that > gets "Renamon's Bra, Renamon's Panties, Renamon's Bra and Armor" and so on to loot.
TL;DR It's basically a additem menu without needing to get the GBO.
