I want to do something a little bit strange in Toolset: I want to create a slider (View) but feed its content via PHP code. Why do this? Because the typical options available in the GUI dashboard interface for Views don't provide the level of flexibility I need from a WP_Query object. In other words, I have a very complex query which I can't express through the visual interface. However, I want to make use of Toolset's ability to output the information in a pre-built format (in this case, a slider).
Is there a way to do this? For example, should I hook into pre_get_posts and just replace all of the arguments?
