Bixby serif font

Request that a set of serif font styles be available for Bixby.  I realize that design consistency is important but usability disciplines are aware that serif fonts are often better for reading-intense applications.  The way I would think about it in terms of the Bixby persona is that Bixby should be smart enough to switch to serifs when the occasion is right, just as a human Bixby would know to wear clothing appropriate for a task.
