Membership 2: How to bypass "memberships" page in signup process

Objective: I want a URL (direct link that can be placed in an ‘a’ tag) that takes the user through this process, without additional steps:

1) User clicks/follows the link

2) User is prompted to fill out the registration form. User submits form

3) User BYPASSES the “memberships” page that lists all available memberships (This step contributes to abandonment)

4) User is prompted to pay. User pays

In a previous thread I was given this URL when I asked for a direct URL to the signup form

/memberships/?membership_id=378

The above URL directs the user to /register/

After filling in the registration form the user is directed to /memberships/ which lists all available memberships.

How can I achieve the objectives listed above?

Thanks in advance
