Sequential task creation with links to other boards

Hi,
I’m having trouble creating new ‘items’ tasks, based on completion of another item, and having a board link follow the auto-created item.

For example:

  1. Board #1: When a status changes, a new item is created in a “Task Board”, with the boards linked & mirror fields created on the “Task Board”
  2. This new ‘task’ has a type assigned “task 1”
  3. An automation is created for the task:
    (a) when status is done AND type is ‘task 1’
    (b) move the item to done
    (c) create a new task ‘task 2’ on ‘task board’

This works… but the linked/mirrored field from board 1 are lost in the process, meaning we get multiple 'task 2’s being created and no way of seeing what item from ‘board 1’ they relate to.

What am I missing? How can I create sequential tasks, all linked to board 1?

Thanks so much!
