An expense came thru the bank feed and is already reconciled, can it be applied to a/p without undoing the reconciliation or deleting the transaction from the bank feed?

Let me be the first one to welcome you here in the Community, @followtheteacher.

I'm happy to share with you some insights about the expense transaction in your bank feed. I'll make sure you'll be able to apply it to bills.

Since the transactions are already reconciled, what you can do is exclude the transaction from the bank feeds. 

Here's how:

1. From the left menu, go to the Banking menu or Transactions menu, then select the Banking tab.
2. Click the For Review tab.
3. Tick the checkbox of the transactions to exclude.
4. Choose Exclude.

Once done, if the reconciled transaction is not yet in the Accounts Payable account, you need to edit the transaction and post it. You can now apply the payment to the bills. Make sure there are no changes in the amount to avoid issues with the reconciliation. 

You may also consult an accountant to avoid messing your book. If you don't have an accountant, you can check this link: Find an accountant.
