Can you allow offers after bidding starts?

[tellmuluvm]

Hi, I have several items listed without selecting "allow offers." There are bids on all but 1 item. A buyer messaged me that they want to buy 2 of the items; one with bids and one without. Is it possible for me accept an offer for both items? The "allow offers" button is gone now that the items are listed.

Once the item has had a bid offers are no more.   The button disappears and all pending offers and counteroffers immediately automatically expire.
