Fixing Bulwark with 1 button

I have noticed that Bulwark has issues with having the Parry and Block on the same button.
Would it be feasible to separate the two?
Since Bulwark is the only class that has dedicated instrument for blocking (his shield), isn't it possible to separate it from the weapon? If we could bind the block function for the shield to the "Swap weapon" button (which is not used at all with Bulwark, by not having a primary weapon),  probably the use of the class would improve.

It could be either a hold or a toggle function, however it can be implemented.

The same could be implemented for the Assault, changing whether you want to use it horizontally, for the slam attack ro for the vertical extended dodge function.

(sorry if thread and/or ideas are a duplicate)
