[L4D2] Survivor Inaccaracy after Infected Hit Off Console Command?

Where is the command for this? if there isnt a cvar for it can someone make a quick plugin that disables all survivor inaccuracy after an infected hit.

Thank you.

This can be achieved by patching the call to "CBasePlayer::SetPunchAngle" inside "CTerrorPlayer::OnTakeDamage_Alive". If you go with the method of changing the survivor's "m_vecPunchAngle" netprop, the screen will be jittery after each hit.
