If you find yourself copy and pasting the same set of blocks again and again, and making minor changes to each copy of the set of blocks, you may want to try using a block template.
Block templates are reusable, changeable sequence of steps that makes it simple to repeatedly duplicate generic structures without having to copy/paste blocks.
Block templates can contain one or more steps and blocks, and are accessible through the Library tab on the left vertical step sidebar.
You can also customize the name and colour of block templates.
To repeat the same user flow again and again (same blocks without making changes), use a component step.
