upgrading

I mean I cannot plan the route of the planes for example when they taxi to terminal or runway. Which is something you can do with the Pro version.

Hello all, I was hesitant between tower!3d the normal version or the pro version. I just paid 30 dollars for nothing, It was not clear on the website what "Advanced ground radar (ADIRS) and Much more and complex commands" would mean? What did they mean my "much more"? I wasn't sure, so I bought the normal version. The second I saw that I cannot assign plans to the paths I want I knew I want to upgrade. Voice recognition is not important to me. I love the game and I would like to upgrade to the pro version. Is there a way to do that? or did I just pay 30 dollars for nothing. Because the normal version of the game is not challenging and plans keep hitting each other because you cannot assign them to certain paths. Many thanks.
