ToDo: Creating a completed task?

Google Keep exports it's tasks to Google Docs as a bullet list with completed tasks crossed through.

You can copy and paste the list into the add task space in the desktop version and it creates the individual tasks, it works great!

But why not also create completed tasks so as to maintain work history moving between tools.

Is there any character you can add when creating a task that it will be created as completed?

Any hacks?

Or is there somewhere I can add a feature request?
