I didn't originally find this. I saw this for PC and confirmed it works for switch If you name your character item values surrounded by brackets. EX:  when game references your name, it will spawn items instead. In this example there are 3 items. You don't always get all 3, but sometimes you do. You'll always get the first one. The video doesn't mention it, but you can also name an animal while buying it for a one time spawn. Then you can rename the animal after. If you don't want to have a weird character name you're stuck with, then this can be pretty nice.
