Sense - Image Banner width fixed, same as grid on slideshow

Hi,

I am using the Sense template and would like to have the Image Banner be the same width as the other sections on the website rather than the full width of the screen.

On the “slideshow” option it allows you to select FULL WIDTH or GRID. The GRID option makes the width the same as the other secions. I want to do the same but for an Image Banner.

TIA
