Mouse Support Razer Synapse

I'm not sure this is a bug, but I notice that when I use my Razer Synapse Mouse, Razer Mamba, that not all the buttons are recognized. That isn't the biggest problem, and yes, I did read the issue about support. However, I would like to request if there is a button mapping capability for side-scrolling. When I push to the R-side on the scroll wheel, it is recognized as Scroll Up, and similarly for L-side scroll...But there is no similar feature on BTT. I am wondering if that can be done?
