In the picture below I show a report I've created and the default report shown for node information. Basically I created mine because I wanted the one shown to show more calculations on disk stats, other than just space used and size. I'm happy with my report except I wish there were a visual indicator of disk space left percentage like the default report has. So my two options/questions are:
1. Can we insert that visual graph into our reports?
2. Can the default report they use have columns added to it?

Thanks.
