Possible to disable or change spot light shadow filter?

Hi, sorry if this is the wrong place to post this.

I'm wondering why point lights have unfiltered/pixel-perfect shadows and why spot lights do not and if there's a way to disable filtering on spot lights.



Left is a spot light shadow at the highest resolution, right is point light at highest resolution. I know spot lights are cheaper but wouldn't it be even cheaper to leave the shadows unfiltered? I'm doing a flat/retro style and the blurry shadows really conflict with it so it's rather important.

Thanks.

 

I don't know, but I'm getting the same issue in Unity 5.4 :\
