Change default naming conventions in PhpStorm 2016.3

Question

I work on a project with some specific naming conventions which are different from the default ones in PhpStorm 2016.3. For example, when I need to create a method and start typing its parameters, autocomplete tries to help me in the following way:

function meh(MehObject $mehObject, AutoComplete $autoComplete) {}

I need something different to appear by default as I type, though:

function meh(MehObject $meh_object, AutoComplete $auto_complete) {}

If I succeed changing the convention in PhpStorm, I'll only need to press enter once after $ , and a valid name will appear. As for now, I need to type the full name with an underscore (or even a few underscores). That is unproductive.

How do I change the default naming conventions for the given example and other cases in PhpStorm 2016.3?
