Right now, when developing routines, you can only select from a list of canned comments for Alexa to say. For example, I have a routine that turns on my bedroom lights to 20%, then reads the weather, then she says a pre selected comment like, "looking good" or whatever. These could be in a list of hundreds of similar comments that are completely randomized so that you aren't getting the same exact response every time you generate the routine. It would also be nice to add your own customized comments as well. It would keep it very interesting and add to the interest of what she'll say next.
