How to lower resolution of texture on model

Is there a way to use a lower resolution version of your texture in the 3d settings than what you uploaded it as? For example using the 1024 mipped version of a texture as default rather than the uploaded 2k version?

What’s the use case?

We automatically generate every power of two resolution between 32x32 and your original size. Then, we choose the best resolution we can to balance quality and performance, depending on the device being used to display the model.
