I would like to be able to create a manual transaction in advance of the transaction occurring and have the incoming synced transaction automatically "merge" into the manually created transaction.
This is a great feature that YNAB has that allows me to proactively manage my finances.
Use Case:
I make a purchase on Amazon for $15. In the moment, I already have Lunch Money open so I decide to just throw the transaction in since I can categorize it right then and there.
Later, when the transaction syncs from my credit card, it should automatically detect that I created a manual transaction and "merge" the incoming transaction details with the manual details.
