How can I make Chrome autocomplete search results from Startpage?

The Chrome address bar will autocomplete my search results if I use DuckDuckGo, which is nice, but I want to use Startpage instead, since it gives Google results. However, when I install the Startpage extension, there is no search autocomplete. Is there a way I can make the Chrome address bar autocomplete searches when using Startpage? For now, I use the s! bang in DDG to search with Startpage. Thanks!
