Allow customization of Blazor Razor component formatting rules

Hello, I'd like to be able to customize some formatting rules in my Blazor Razor component files. Mainly the element attribute indentation rules.

The default formatting rule is to place the first attribute on the same line as the element start tag, and following attributes keep the indentation of the initial attribute.

<SfTextBox CssClass="e-field"
           Placeholder="Tag" />

I would like to customize the formatting rule so that the first attribute will be on the line below the element start tag, with a single indentation from the element start tag and have the following attributes to use the same indentation.

<SfTextBox 
    CssClass="e-field"
    Placeholder="Tag" />
