Could you explore adding an indicator to the line item of tasks that indicates a task has one or more subtasks (or checklist items) recorded?

Currently there are icons to indicate that a note has a textual description (one can view the contents of the description field by hovering over this icon) or color-based icons to identify that a task is checked as "Doit Now" or "Today". Could we get something similar to indicate the presence of additional information in the subtask field?

I'm sure that I've completed a task not realizing I had made a checklist of items in it, only to realize later that I didn't reconcile that each of the items had been satisfied.
