exclusive plan > mandatory

Hi,
I use CBSUBS 3.0 on CB1.9 and Joomla 2.5.8
In component manual I read
"If plans of the same level are marked as “Exclusive”, then it is mandatory that
users be subscribed to one of these plans at any given time."
How can I set plans to be exclusive but not mandatory?

In other words, a user subscribe to plans not during registration, but only after.
It means that there are registered users that can navigate some parts of the website without having any plan subscribed.
But if he want to subscribe a plan from the list available, he can subscribe only to one of them.

So, how to conciliate exclusivity of plans with the fact that they shouldn't be mandatory?

Thank you

Using conditionals as configured on the Workflows tab of your plans. First set your plans as non-exclusive then set conditionals to hide/show based off other plan selections.

Just set none of your plans to display on registration or have an exclusive free lifetime plan for them to pick.
