Proposal: Can we have a shortcut to create a copy of ControlTemplate?

Summary

We understand it might be difficult to implement a working xaml preview/editor. (althought it's already 5 years after #2975) But can we have a shortcut to quickly create a copy of a control's ControlTemplate, that is like the single most important feature of xaml preview?

Rationale

So I am trying to modify a small ui detail of NavigationView, so I go to packages, find generic.xaml, and find the NavigationView's ControlTemplate by searching TargetType="NavigationView, and I found none. Then I tried DefaultNavigationView, still none.
Then after wasting for several minutes of my life to scroll the 36000 lines of xml , I found it under this

    <Style TargetType="controls:NavigationView">
        <Setter Property="PaneToggleButtonStyle" Value="{StaticResource PaneToggleButtonStyle}" />
        <Setter Property="IsTabStop" Value="False" />
        <Setter Property="CompactPaneLength" Value="{ThemeResource NavigationViewCompactPaneLength}" />
        <Setter Property="CornerRadius" Value="{ThemeResource OverlayCornerRadius}" />
        <Setter Property="Template">

First of all, why does it still have a useless controls: prefix after like 4 years since winui2?

And why can't we have nice things? Why can't we just have a feature in visual studio that I can quickly edit a controltemplate when I right click on the control's xml?
