Membership plugin skip Subscription page

Hello, the plugin is very convoluted in terms of programming. How would I skip the "choose" a subscription page, if we only have one subscription to choose from. I did a Redirect to next page, onsubmit, but it causes the page to show for 1/2 sec. Any shortcut or direction you can give me.

1. Register name/pass
2. Choose package (Best way on HOW Skip?)
3. Make payment
