Content drip feed

Hello,

we need to build educational site based on WP and we are testing your
plugins. Unfortunately we did not find possibility to mage "content
drip feed".

We need to ensure, that

1/ learning video 2 will be available 7 days after registration of a
specific member, video 3 in 14 days, and so on

2/ video 2 will be available after having opened video 1 (in some
cases is this done by manual buttor, where user must click on it and
check, that the user has vieved the video)

Does any of your plugins support this feature or a kind of alternative
of this feature?

i.e. s2 members plugin supports this in their free version.

Thank you
