We do offer positioning for native ads within our WordPress plugin.
Check out our plugin here and once it’s set up, click “Zone Options” in the Broadstreet submenu to see the different positions available.
Since it’s sort of theme-dependent, there are some themes out there that don’t call the necessary hooks to make it work all of the time.
Beyond WordPress, or if you have ideas on positions we don’t provide, our ad Zones can be integrated into a theme manually, which is a job for anyone WordPress/programming savvy.
