Not as such.
But it is not difficult to do.
Just go to your Selling page, click on the button that will tick off all six of your listings. Click on the drop down button that allows you to Add a Note or End Your Item.
Make a note to your self when you ended the items.(optional)
End them.
The listing, pictures and all, will go to your Unsold page. When you get back from vacation, you can either Sell Similar or Relist them. You can leave them unsold like this for 90 days.
You will be charged for the new listings, but the small amount is well worth the peace of mind.
