You can select one or several additional commands that will be executed after the Run instance command succeeds. The commands will be added to flow in the order in which they are listed in the Additional Commands table. Additional commands are used to manipulate volumes, tags and instance properties. The Maestro CLI analogues for these actions are or2-create-and-attach-volume, or2-set-tag, and or2-set-ptoperty.
For more details on this functionality, please, see our Maestro CLI Reference Guide, Sections "5. Instance Properties", "8. Working with Volumes", and "11. Using tags"
