Selling groups of items on Item Market

When listing items for sale on the Item Market, I know how to list an individual item or compact and sell ALL of them from the Inventory section.

How do you make a group of 10 items to sell on the Item Market?

There's no way to sell multiple items on the item market unless you can get that amount of items in your inventory and compress them. I believe there's suggestions floating around about designating a split of items from the inventory but for now it just decompresses them back to their individual status (1 treat, 5 uses for bags, 10 for cubes etc.). You can put multiple items on the market at once using the inventory manager(thought the items will be in the single group created in your inventory or individuals) or create a trade with multiple items in it. 

Thanks for the info, even if it wasn't the answer I was hoping for! ;)
