Definitely! That’s exactly what the external data functionality is designed for; see here for details:

When you create a task via your application, store your own ID in that task’s external data. Then when you go to create a task, you can first query for that ID to see if it exists before you create the new task.

This field is just like any other field on a task I believe, look at examples of how to update a task, and target that specific field. Let us know how it goes.
