Copy and Paste Chart

Summary

Is it possible to change the grid a chart links to?

I have created a chart in Management Reporting and would like to copy and paste it to use it as a basis for creating a similar chart without building the new chart from scratch.  I've managed to copy and paste the chart but they both are linked to the same Source Grid so any changes I make affect both charts.  It is possible to change the source grid for the 2nd chart only?
