lms tutor pro – prevent buying course that has a pre-requisite course

Hi there.

I am using LMS Tutor Pro. I have created two courses. Basic and Intermediate. The Intermediate course has the Basic as a pre-requisite. I want to prevent a user buy and pay for the Intermediate course if he hasn’t payed and completed the Basic course first.

Right now, the user can buy and pay for the Intermediate course; however, he can not access it until buying and paying for the Basic one.

Is there a way to prevent this?
