Metatrader script to remove rectangles with certain description

I need to have a quick script created that will remove all rectangles found on the charts that have a certain description or name. The script will do this when it's dragged on the chart - It will look for all rectangles whose NAME contains a certain text, default: aII_SupDem - It will look the those rectangles and remove them from the timeframe where the script has been dropped - An input variable called RECT_NAME is needed with default value = aII_SupDem That should be an easy thing to do.
