List Multiple Items for Sale?

Is there a way to list multiple items for sale? I have dozens of apples and sugar cubes, etc, and the idea of clicking each one to sell them as single listings is very daunting to me!

If you go to your inventory manager you can use the radio buttons on a single page and input the prices then update the whole page to listed at once(this option has less load time than going through individual treat pages). Or if you want to use the marketplace you canclick on the first item then shift+click on the last item of a group you'd like to offer in a trade and sell items that way. (You can use ctrl+click to get multiple items in different places on the list). 
Other than that you can always compress items and sell them as a dingle unit.
