Controller Trigger Deadzones

I've been experiencing this issue since launch, but with the new SMG, I genuinely can't even use it properly. In game I have no ability to use weapons that have a charge mechanic where I hold down my right trigger, so I just ignored them completely in Season 1. The reasoning for this is because of there not being an option to change trigger deadzone, and even on my deepest press, the weapons won't work as intended. I can only use the new SMG in a short burst or tap fire, and lose the capacity to shoot it at full-auto. I hope there can be an addition in game for controller triggers because it's unplayable atm.
