With the new Collections that people are picking up we wanted to provide some additional flexibility on the SmartPost page to make it easier to include/exclude certain kinds of items. You can use this to post your Disney Collection items separately from your other inventory, for example. Or you could post all of your red items, or everything non-floral, etc. Filtering is all based on attributes. After defining your attributes filters you'll enter an Album name template, which is used to generate album names based on the attributes of your currently listed items.
