Turn Off Calendar Location Suggestions

I sync my work Office 365 account to my iPhone and use the built in Mail and Calendar app. My company also syncs everyone's contact to my iPhone, over 2000 contacts.

Whenever I use my phone to create a New Event in Calendar, the location field takes a very long time to populate. This seems to be because the iPhone searches all the saved contact locations and places nearby for suggestions. Is it possible to turn this suggestion feature off? It would save me a lot of time.
