How to combine multiple records in a business event notification?

Hello,

We have a business event that needs to send out email notifications when an inventory item reaches a certain age. The email should have all the items listed together - as opposed to sending out multiple emails. 

I currently have this business event set up:

As of now, if more than one row is inserted, it only adds one out of the two items to the email subscription. I’ve even tried adding multiple datafields to the table (as shown below) but it does not work. 

The expected Result should be something like this:

How can I achieve this? I appreciate any help or advice you can offer, thank you!
