Matching receipts after transaction had been posted

I believe in getting accounts updated as quickly as possible to keep balances in check.  When using the BANKING function, after clicking update, the transactions start to populate the REVIEW section.  However, because I have hundreds of AUTOMATED RULES, these transactions get automatically entered.

This Receipts App on my (and my client's) phone is a wonderful tool.  In the past in order to attach receipts to transactions, either scanning or picture taking was required then saving to a centralized folder Onedrive or Google Drive), and then uploading or attaching it to the transaction itself.

So then, what's the issue? Using the Receipts App is great for getting the receipts in for review.  However, I never get the option to MATCH it to an existing transaction.  I do need to edit the details for the vendor name, as well as the accounts of which they were paid from and where they get expensed to.  After this is done, I only get the option to CREATE the expense.  If I choose this option, I now have two entries for the same transaction.  I then need to delete the automated transaction, which then causes yet another issue.  I will need to go to the Rules, turn off Automatic, delete the transaction, go back into Banking Review for that credit card, choose Exclude from the list, then go back to Rules and turn automatic back on - PHEW!!!  This is a hell of a lot of work for one simple transaction. Okay - just convinced myself.  Go back to scanning or picture taking and manually upload the receipt - TADA!  Problem solved...

Is this APP only meant to be used in ONE direction?

Is there a way to grab the image already in the review section and attach it to the currently uploaded and entered transaction?  If so, where are they stored so I can grab them?
