Blog URL: I want ".../blog/category/post-title "

In Settings -> SEO there is only options that add a, quite unnecessary, "entry" moniker to the URL if "simple" isn't chosen.

I only have 2 options is seems.

1. If I choose "simple" it does not include "entry", however, this does not include "category" in the URL either. Example: ".../blog/post-title"

2. If I choose any other option is always includes "entry" in the URL (back end "view"). Example ".../blog/entry/category/post-title"


How do I remove the "entry" from the URL but keep the "category"? Example ".../blog/category/post-title" ?

Thank you.
