The Meaning of Life, the Universe, and Everything.
Are you aware of the already in-game command that allows the user to keep all of the items in their inventory? I know that's not exactly what you're requesting, but I was just mentioning it to keep you from desiring something that's already at your fingertips. Anyways, other than mentioning that, there's nothing much that a non-coder like myself can do, apologies. Hope someone comes along who will help out!
