Add Template Task to Multiple Parent Tasks at Once

[#1]

It would be great to be able to add a template task to multiple parent tasks at once, instead of only being able to add to one parent task at a time. That way if there is one task series that I want to go within each month in my project, I can easily add it to every month's parent task at once instead of having to keep re-entering the template and individually adding those tasks in.
