Is there any way for a Sprite Renderer to use mipmaps?

I’m developing a 2D game which zooms in and out sometimes. So far I was using quads with a texture. With high resolution bitmaps, his correspondent mipmaps and trilinear filtering zooms look great.

Now, I was trying to take advantage of the new 2D features of Unity and was replacing my textured quads with Sprite Renderers but hitted a problem. My zooms now look horrible because it seems that Sprites have no mipmaps.

Is there any way to achieve nice zooms with Sprite Renderer or do I have to stick to textured quads?

This Is it possible to turn on Mip Maps for a sprite? might be of help.
