Hi, it looks like you are using the default theme in your images. If I remember correctly the default theme does not allow for that (I could be wrong I'm running a import and cant check right now) you may have to use another theme for your desired effect. We have 40 user created themes in the download section and many do exactly what you want. Here is a link, have a browse and see if anything takes your fancy.
