[Help Wordpress] Fixed width main slide with nearby slides enabled?

Hi,

So far I have the slider set up with Nearby Slides enabled and the width of the current (main) slide is set via the 'Center area ratio' value, however ideally I'd like the main slide to always be set to be 980px.

Is this possible? If so, how do I implement it?

Kind regards,

Adam.
