Free / Sample Lessons

I am coming from LearnDash on WordPress and one of the features that I like is the ability to make any lesson as free (sample lesson).

That way I can choose to give the first lesson for free or to give the first lesson in every module for free. However I want to make it.

The main benefit is that I don't have to redirect people to my site or other place in my HeartBeat platform in order to get the lessons I want them to have for free.

Would be great if we have that feature. Thank you!
