Cancel current/all interactions in queue

Hi, I'm fairly new to modding the sims but experienced in coding. I'm messing around with mod constructor 4 and making simple mods, so far I've been able to do a lot just using the tool. I was wondering if it would be possible to implement some sort of action to cancel the interaction a sim is currently doing (or even has queued up). There doesn't seem to be a direct way to do it in mod constructor 4 but I do see there is a custom tuning option, which I don't really know how it works since the documentation is non-existent. What I would like is when a sim receives a buff they cancel all actions and do an animation, I've got the animation part down but the sim will only do it after you manually cancel the interaction or it finishes on its own. Is this possible with mod constructor 4 or do I need to learn Sims 4 Studio to do this? I figure the ability exists in the game since the passout function works like that.
