Can I use other (larger) color spaces than sRGB in Unity?

I would like to display the colors of my images more correctly in Unity. In Photoshop I work in ProPhoto RGB or sometimes Adobe RGB. In the current workflow I have to convert images to sRGB to import and view them in Unity. This makes the colors appear incorrectly compared to the originals and also creates extra (unnecessary?) work with the conversions, since I usually handle large amounts of photos.

So, is there a way to replace the Unity default sRGB color space with ProPhoto RGB or Adobe RGB?

Happy for any help on this.
