Copying and syncing tasks between different planners and groups?

Hey all, 

Did a search and could not find anything, so here we go.

I understand I can copy tasks to different plans within the same team and to different teams, but is there a way for these tasks and check lists to sync with each other?

We have multiple instances where one task on our plan coincides with another teams task on another plan and so on. Obviously situations occur where the task is completed more than once due to lack of communication between teams. 

I understand that you can copy complete plans and that they can sync, however I am looking for the same thing but only with copying/creating the same task to multiple plans on multiple teams. 

Thanks for any help.
