Feature Request: Free Trial per level


I know this plugin hasn't been updated in a while however I would like to request a new feature.

Free Trial per level for x amount of days; the ability to provide one level as a free trial is good.

However many saas platforms tend to limit features based on level/plan while allowing the user to sign up for the plan of their choice for x amount of days Free. This allows the user to completely experience the the plan and provide better conversion.
