Feature Request: Make Subtasks widget invoked by text that can be placed anywhere within a Project note

[andylynchpe]

I find the Subtasks widget very helpful but I wish I could choose where to have it placed within my notes instead of only at the top or at the bottom of the page.
Feature Request:

• Have the ability to define where the Subtasks widget will appear on a page by inserting some block of code or other identifier in the page.

@andylynchpe Can I recommend the use of a base, instead?

views:
  - type: tasknotesTaskList
    name: Subtasks
    filters:
      and:
        - projects.contains(file(this))
