Being able to edit the Summary Number description

[#1]

We are able to edit the label for a graph visualization however we are unable to edit the grey text in the right hand corner of a Summary Number. Many of my metrics are lengthy and these descriptions become very large when creating Summary Change visualizations.

My advise would be to hide this label (uncheck "legend visible") in visualization settings and edit the description of the report (right click on the title).

Description will be just under the title and not in the bottom right corner, but at least you can write whatever you want.
