Useful Tools & Suggestions:

If you’re appending items to a list, Push List Items is a solid partner it lets you add new entries to the end just like append, but with more flexibility if you’re working step-by-step. And if the final result needs to stay clean or follow a strict format, Trim List Items helps tidy up any trailing spaces or formatting issues after the update. Super handy when you’re building lists dynamically or combining inputs from different sources.
