Unity UI More Mip-Map Control for UI textures / Atlases?

So, I'm using a lot of UI in my projects. And I love the UI system being so responsive. And to that end a lot of my graphics end up getting mip maps because they are used in different situations and I'd rather have them a bit blurry (with a lower mip map texture) than scaled down and look weirdly crisp. Especially when it comes to icons.

However there's very little control over the MipMap settings of textures, and none for Atlases. Are there tips on how to get around this? Any best practices?

 

For example, the super low mipmap resolutions are never needed in this context and could just be skipped to reduce file size
