Simulate follow camera using "Scriptable" property?

Alright guys. So I am creating a game where the camera is following the player and changing where it's facing based on the players direction. You guys are probably asking, why don't I just use the "Follow" property in the CurrentCamera? Well, I don't have enough control over it. I want the camera to follow the player and transition it's direction in a specific smooth-ish type of way, which is not how the regular "Follow" camera works. So I was wondering if anyone could think of any way that I can sort of simulate or recreate the "Follow" camera using the "Scriptable" camera property. Any suggestion helps, thanks!
