Kind of a weird one but... In a sales order, I'm trying to get a line item that's within a subtab of a tab on a Sales Order... ☠️ if I inspect the line, the id looks a little like this

recmachcustrecord_pacejet_transaction_linkrow0

, which I'm guessing increments based on the row... but I'm having a hard time figuring out how to query/access this information within an afterSubmit user event - can somebody give me a push in the right direction? 🙂
