All companions give the same gift items. Instead of getting leaves or whatever from Sarah, you’ll get ammo, credits, or a digipick.
I set every companion gift pool to a new one that I made in xEdit. No matter who your follower is, they will you a small amount of ammo, some credits, or a digipick (rarely, 2 digipicks).
Until official mod tools are released, these mods are considered experimental.
To install this, you’ll need to add BetterGifts.esm to your Plugins.txt or StarfieldCustom.ini.
