Text box on Image - Grouping into a single image

Is there a way to group images and text box into 1 image, so it is easily moved on the desktop?

I am attempting to create a legend based on the the Trend lines within the Bar Chart.  So far I have created separate images and text box to explain the image representation.  I would like to be able to select all the persative images/Text Boxes to create a single image.

thanks,

Karen
