There isn't an option to do this in Exchange at this time. You are welcome to edit Exchange to accomplish this if you'd like and feel comfortable doing so. You'll need to edit the template files do to accomplish this. Instead of actually editing the template files, you'll copy them and place them in directories you'll create in your theme. At the top of each file is information about where you would want to place that specific file.
Let us know if you have any additional questions.
