Current structure (Things): parent (date), task, subtask.
Parent contains list of Tasks
Task contains link to Parent and list of Subtasks
Subtasks contains link to Task
Logical structure in my head 
Now the challenge I face is when trying to make a copy
I want to make a copy of the Parent, eg. current days tasks and subtasks to another date.
What is the best way to go about this ?
Creating the new Parent and stringing up the tasks I can manage, but to copy the subtask and make them related to my copied tasks is what gives me a headache
What would be the best way to achieve this
API workflow, post to API, Loop over task and subtasks or is there a really simple solution I am missing?
Any pointers would be appreciated
