The title is the whole question: Is it possible to use tile templates with secondary tiles in a Windows Store App? Also can secondary tiles animate? It looks like the answer is no, even in Windows 8.1 but maybe I am just missing something. Here is a link to the Tile Template:

Here is a link to the SecondaryTile class:

It's weird because this seemed like an obvious oversight in Window 8 and they revamped secondary tiles a little bit in Windows 8.1.
