UE4/Wwise - Firearm Full Auto Issue

So, I'm now trying to set a blueprint up. I can get weapon's ROF and pull an RTPC from it. To avoid situation when there's only one shot fired but you can hear two gunshots I decided to post a fire weapon event and wait one ROF cycle (e.g. 0,08 s for M4A1) before starting the full auto loop. Then, after the trigger has been released, an appropriate tail should be played - I could of course just loop it with the gunshots, but I figured it sounds better without it during full auto, as it's solved in Insurgency: Sandstorm. I wonder how should I organize it in Wwise project - as it requires four Wwise Events (semi auto, full auto, burst for certain weapons and the full auto end tail). Or is it possible to achieve with less events?
