How to preview <App> included .ux file instead of MainView.ux?

Hi,

I would like to preview separated Class Resource .ux file with mock object for debugging. I hope fuse preview get MainView.ux filename option.

https://www.fusetools.com/learn/fuse#-class-resources-

example:

<!-- DebugExampleView.ux -->
<App Theme="Basic" ClearColor="#eeeeeeff">

  <JavaScript>

    module.exports = {
      text: "test.",
    }
  </JavaScript>
  <ExampleView/>
</App>

<!-- ExampleView.ux -->
<Panel>
  <Text Value="{text}" />
</Panel>

Thanks
