Per Point Light Custom Shadow Resolution

I would like to set the shadow resolution of a point light indeferent to the shadow quality settings. At default UE4 uses a shadow resolution of 1024. However it would be nice to set the resolution for certain lights at a far lower value. This way it is not only possible to save performance but also fake better soft shadows:

The first picture has set r.Shadow.MaxResolution to 128 and the second to 1024. Shadow Quality was set to Epic and Shadow Filter Sharpen of the point light to 0.

Could it be possible to expose such a variable to the light component?

I second this. It can also greatly help optimizing.
