Add line conditionally to saved search

Hello,
I am attempting to put a search together that is to be used to import small balance write-off's. I need to set the account the debit posts to and the account the credit posts to, but due to the import template can only have 1 account column listed and the nature of the journal entries require a debit and credit on the same transaction. I do not want to do separate imports as that would be cumbersome for my cash app team.

I am running a transaction search and pulling in Amount and Amount Remaining, but cannot determine the logic so the "else" appears.
