I think most are happy with flagged for review available under the Pro subscription, its an improvement to the previous transactions page. Adding another status seems like a niche need and there are other ways to accomplish this. See below.
@apskiprop, guidance for default to “Needs Review” is covered HERE.
@keithschuster,you can have change all transactions to import under the “Needs Review” window. Once a transaction has been reviewed, you can remove the red flag and it will move to the standard transactions window. May not be your preferred method, but it should accomplish what you need.
