Smooth 2D Platformer Camera in Cinemachine with C#?

Hey guys,

The wonderful devs from Cinemachine invited me to post my question here which I already asked in Facebook.
I came across an issue while playing around with Cinemachine.
I wanted to mimic a Super Mario like camera. Something, I thought, Cinemachine can be perfect for due to its smooth transition and damping abilities.
However, I cannot seem to achieve a satisfying result as C# does not let me enter some CinemachineVirtualCamera stats.

What do I want?
The camera needs to be centered at the 2D player in idle mode (already coded via: using Cinemachine;). When the character moves, the camera should make a smooth transition to an offset to show more of the level in running direction.
So, I need to constantly swap between a + and - offset, depending on the direction of the player, and back to 0 offset when standing again. (Might also require a dead zone and damping that moves with that offset)
I added two images to further explain my desire.

However, I cannot seem to create dynamic (and smooth) offsets like that with its inspector settings and, even more important, I somehow cannot set the Aim / Body variables like Tracked Object Offset dynamically in C#. The code just does not show any options like <CinemachineVirtualCamera>().Composer.TrackedObjectOffset.X or something similar. I also added one image to show which variables I mean.

I would love to get a reply by the experienced people here. Maybe there is a great and easy solution with Cinemachine I currently do not think of. Thank you so much in advance.

 

If I remember correctly, this presentation about sidescroller (2D) cameras was specially good:

Maybe it can give the Cinemachine team some ideas (if they haven't seen it already). I think very few tweaks are needed to make Cinemachine work great for 2D.
