Under Actions, before move, click "Send Confirmation"
Then, you'll be prompted with the confirmation screen, where you can prepare and send confirmation.
On the right side, click "Edit"
You'll now have the option to "Show available steps to add", click into that
It'll now give you the option to choose additional steps to add to the confirmation being sent.
You also can choose, by the arrows on the right, the order you'd like for the steps to go in.
Once you're finished at the top, and no attachments to be add at the bottom, click "Send Confirmation".
Now you're all set!
