SSRS 2008 R2 Gauge Panel Resize

I have a SSRS 2008 R2 report with a Tablix.  One of the columns in the tablix needs to be displayed as a Red/Yellow/Green indicator. I have a Gauge Panel with a ThreeUnrimmedTrafficLights indicator in this column. The problem is that one of the other columns needs to grow when needed to display all the text and when that happens the row height changes and the Gauge Panel then also resize which means the indicator now looks bigger. I do not want this to happen.  The indicator needs to stay the same size. Any ideas of how I can force the Gauge Panel to not grow with the row height?

Thanks
