Assigning owner of subitem through automations

I am working on setting up a board that would have subitems created via automation when a status is changed. I would like to figure out if when the Owner of the parent item is set, is there an automation that could trigger owners of subitems?

To add another layer to this, there may be multiple owners of subitems. I added an Owner (by Role) drop down and set this up automatically in the automation to identify if it would be assigned to ‘owner 1’ or ‘owner 2’, as an example.

Is there a way in which I can set an automation to fill in the owner based on what was assigned in the parent item?
So as an example: Person A is assigned as owner 1 on the parent item. I need Person A to automatically be assigned to certain subitems.

Has anyone been able to tackle this or something similar?
