A "clean" way to modify indent distance of list items, using custom Theme?

[yccheok]

I have read through #322

Currently, this is how I modify the look n feel of markdown.

    struct MarkdownView: View {
        @State var markdown: String

        var body: some View {
            Markdown {
                markdown
            }
            .textSelection(.enabled)
            .markdownTheme(.melonoteTheme)
        }
    }


    // Copy and paste the code from https://github.com/gonzalezreal/swift-markdown-ui/blob/a9c7615fb50323069c2979c69263973aa1b24a8f/Sources/MarkdownUI/Theme/Theme%2BGitHub.swift

    extension Theme {
    public static let melonoteTheme = Theme()
        .text {
            ...

By using this method, I can customize things like heading size, heading color, ...

However, I would also like to change the indent distance as discussed in #322

I prefer to perform it via "Theme", so that it will cover all cases.

I believe that, I need to modify https://github.com/gonzalezreal/swift-markdown-ui/blob/c0daf6eb79d97964180f3113868c990bd1c4a007/Sources/MarkdownUI/Theme/BlockStyle/ListMarkerConfiguration.swift , from

.relativeFrame(minWidth: .em(1.5), alignment: .trailing) to .relativeFrame(minWidth: .em(0.5), alignment: .trailing)

What I would like to do is, create an entire new ListMarkerConfiguration.swift via copy and paste, so that it will cover everything.

But, how can I apply the new ListMarkerConfiguration into my custom Theme?

Thank you.
