Creating and maintaining 144 nearly identical pages may not be the way to do. You can probably accomplish what you need with a single page and a little scripting, or some sort of gallery. What are you actually trying to create here?
You can create Commands from the History Panel.
1) Open History Panel (Shift+F10)
2) Select steps or group of steps (Shift or Ctrl+click).
3) Right click and Save As Command.
4) Saved Commands are displayed in the Commands menu for future use.
Commands are useful for things you do often but they are not a substitute for DWTemplates or dynamically populated site pages. When a site is bigger than 50 pages, you should be thinking dynamic instead of static.
