I felt inspired by the Packing List episode a few months ago, and I finally got around to building out my dream packing Shortcut. I used this shortcut as a framework. My shortcut takes a dictionary of “essentials” that come with me on every trip and allows for me to choose from a list of “optional” items. The list then gets sent to Things where it’s compiled with the headings of each section.
It can probably be simplified, but I hope you enjoy it!
