tengo el siguiente problema si alguien me ayuda gracias

Hi, I'm new in the forum and pag. I already see that it is a great community and I like to be part of it, I have no experience creating or modifying that is why I write this post. I wanted to know how to modify the novac bungalow in the willow companion mod. what I want to try is to put a sideboard of weapons like in a mod that I saw of an underground house. (underground hideuot) since it is one of my favorite buildings but comrade Willow does not add his collection in that building from now on thanks.
