I want to output it as a single quotation after entering emmet in vscode.

I am typing emmet in vscode, but I want the output to be single quotation, so I wrote this in settings.json.

"emmet.syntaxProfiles": {
    "html": {
        "attr_quotes": "single"
    }
}

This will be a single for now.

For example, if you type a and press tab, this is what happens.

<a href='>>/a>

However, when you start typing from class or href, it becomes a double quotation.
For example, if the div tag is already written and you insert a class into it or insert a href into the a tag with emmet, it becomes double like this.

<div class="">
<a href="">

Is there a way to output this as a single as shown below?

<div class='">
<a href='>
