Choosing a default paid plan at registration

In a system that I'm developing, there are only paid plans. Actually just 1 paid plan at this point. At the moment, spark requires user to click the "Select" button in-front of the package in-order to show the billing section and to register.

Is there a possible way to automatically have the paid plan selected by default at the point of page loading?

I saw this link but its only for free plans: https://laracasts.com/discuss/channels/spark/change-default-plan

Thanks for all the help in advance.
