How to make Netbeans use single quotes in HTML tag attribute autocomplete?

When I type attribute in tag Netbeans automatically add two quotes:

<form method="|">

I want to make it use sing开发者_运维问答le quotes:

<form method='|'>

From my answer to a very similar question:

Type something like <div class= now your cursor should be in between two quote or double quote characters. You can now type the other type of quote character and it will change your preference.

I'm afraid, but it's pretty sure that double quotes are hard-coded into NetBeans.
