This shortcut requires Things 3. It is designed as a template for selling items online, but can be tweaked to add one or multiple similar to-dos for any purpose.

This shortcut asks for text input where you provide the names of the items you plan to sell, ex “iPhone”. You can provide multiple items on separate lines. This will then ask for each item where you intend to sell them.

It will then add all of the to-dos at once to a pre-specified Things project.
