I have a Deal with a bunch of Associated Custom Objects

(sub invoices). Due to a migration all the sub invoices got created at the same time. I made a “custom\_created\_at” field because i cannot overwrite the original created\_at field.  
I want the deal to property sync the most recent sub invoice based on the custom date
