Combining information from two items

I found this method useful. I have created a “New board” consisting mirrored amount, name, delivery date and service report. However, I would like to know is there a way to make it automate.

What I have done in the automation in “Purchase Order” is create an item and connect with “New Board”. Then, I created another column to link the delivery date and service report. It is manually done for the linkage of delivery date and service.

Is there a way to automate the process? Thanks
