Hello. As John stated it is already possible by using default tags but I think I got why you need such improvement. I thought a small improvement by using new Order Tag Prefixing feature. Maybe not exactly works as you’ve described but I believe that will help.
I’ve configured light red color for default indigents to give an idea about what that Sandwich contains by default. Clicking No Lettuce or Less Onion buttons will turn these buttons to red to visually indicate they’ve removed.
