Disable texture streaming but keep scalability?

Hello!

When I open a level in gameplay mode all the textures are streamed, and it takes a few seconds to load the high-res ones. It looks kinda awkward. I would rather see that the level opens without any texture streaming (I can live with a bit longer loading time).

However, if I disable texture streaming completely, there seems to be impossible to allow texture scalability. And scalability-options is something I would like to have in the game.

So, my question: Is there any way to disable texture streaming, but keep texture scalability?
