Is there a way to automate symbology of rasters to show intervals of 1 from the minimum value?

Any wizards out there that can help? 

We work a lot with raster data and have to symbolize intervals of 1 from the minimum value of each raster. So if the range of values is 3.3 - 6, the intervals would be 3.3-4.3, 4.3-5.3 and 5.3-6. The result ends up looking something like this.

Each column is a different raster and we prefer to symbolize them independently, so the colors are relative to the range of each. 

This gets tedious with larger projects. Can anyone help with automation? 

Thanks for your time!
