login form with optional registration

Hello, I know there is an option to make a login form or a registration form with your plugin but is there also an option to make a form wich on the first page has a login/registration form, wich is hidden if the user is already logged in and then on the second page an event registration?

My usecase is that only people with an account can register for the event but I dont want to place three forms on the page (a login form, a registering form and the actual event registration).

I also tried to work with hiding the registration and login form if the user is logged in and hiding the event form if the user is not logged in but this requires me always placing manually three forms and still leaves me with two forms visible for non logged in or non registered users, as they see both the registration and login form.

Best Regards
