How to best configure a number of single-pane tabs, and to set title?

I found this works but I was hoping it could be written more succinctly.

project:
  root: ~/src/project
  layout:
    tabs:
      -
        layout:
          -
            - cd src && echo -ne "\e]1;project/src\a"
      -
        layout:
          -
            - cd public && echo -ne "\e]1;project/public\a"
      -
        layout:
          -
            - cd dist && echo -ne "\e]1;project/dist\a"

Secondly above the title is set on each tab, and the same pattern works for panes. Could that be configured instead?
