Apply a subscription plan to "free access" accounts

[MartiBarber]

Has anyone figured out a way to apply a subscription plan to the free access accounts?

I know they use the 'Default AC' account profile, which can be edited via some radius attributes on the controller. But i want to make use of the some of the subscription plan features for free access users. 

The customer is looking for a method of providing free access for a set time, say 60mins. Then once that time is up, they want to stop the public user gaining access again until some time in the future (like the next day). I think that if could apply a subscription plan with the "online time" set to 60mins and then set the lifetime of the free accounts to 12 or 24 hours this would suffice. 

So has anyone figured out how to apply a subscription plan automatically to all free users? Or has anyone found a different way to gain this functionality?

Thanks

I guess no one has figured this out...or it is not possible. Shame.
