Anvil render question

[FunnyDevs]

Hi! I have a fragment that returns a new RenderableView with a complex layout. When i use Anvil.render() to update the layout, it update entire renderableView. I would like to update only a specific relativelayout, but if i use Anvil.render(view), it searchs only for RenderableViews and doesn't find realtivelayout.
Is possibile to render only a specific view inside a RenderableView???

Thanks
