WebStorm/PhpStorm double quotes in TypeScript auto import

I'm using TypeScript style with single quotes, double quotes are used exclusively in HTML templates.

WebStorm/PhpStorm auto import adds import statements with double quotes and ruins the style. I guess this applies to all JetBrains products.

How can this behaviour be fixed?

This behaviour is controlled by the following option:

• Settings/Preferences

• Editor | Code Style | TypeScript

• "Punctuation" tab | Generated code -> Quote marks

As of 2017.1 version it's on new Punctuation tab and options are named a bit differently:
