Adding a new column to certifications can be done with custom evaluators, but it’s per type, not per campaign/instance. So if you added a new column per manager certifications, it would show for all types.
You could always either:
- Leave the column value blank (or N/A, dash, etc) for campaigns you did not want it to affect (i.e. ManagerTwo in your example)
- Use a custom plugin to modify the UI to hide this custom column for non-supported campaigns
Alternatively you could achieve this entirely with a custom plugin avoiding the custom renderer if you wanted to package it all in one plugin.

Hope this helps!
