Deleting a subitem between two boards with Same Items Multiple Boards App

Hello. I am using the Same Items Multiple Boards App. I like it a lot. I see one potential issue that I may need to figure out how to resolve. Everything works on my automations to create an item from Board A to Board B. I can update from Board A to B and from B to A. I can also add new items from both Boards. The issue that I am having is that if I want to “Delete” and item or “Subitem” from Board A, it doesn’t delete the item or Subitem on Board B. I think I can logically understand why, but does anyone know a workaround?
Thank you
