Batch Convert / Reproject - How to get EPSG' WKID 3979 on output

RyanP

I am trying to reproject imagery with a specific coordinate system set on the output files. I select an input with the coordinate system set to the desired EPSG WKID (3979), however the output files have a custom coordinate system set?

INPUT: 
NAD_1983_CSRS_Canada_Atlas_Lambert
