Talent Ratings: Loading Comments for Performance Rating via HDL

Summary

Looking for guidance on loading comments via HDL for Talent Rating> Performance Rating

Content

Hello Experts,

We've loaded performance ratings via HDL for our population. However, we have a separate external score that also needs to be referenced by managers and administrators as part of the performance process. I would like to place this rating in the comments section, but as of yet, I've not been successful in identifying how to load that value. 

If someone has had success loading comments and can point me in the right direction with a sample layout, or any additional information, it would be most appreciated.
