Controller: How to bind Swap weapons to right side Trigger only?

Hi guys.
I'm playing with the controller and it works very well for most of the stuff, except some things. One of them is this one:

Playing with mouse and keyboard I can swap weapons just pressing a single key, instead playing with the controller this function is binded to Right Trigger + Right Stick Button.
So I have to press two keys, one of which is slow and clunky. This combo is slow and prevent me to play efficiently the builds that need to swap weapons often and fast.

Is there any way to bind the Swap function to just the right side trigger?
