Just gunna bump this to post a suggestion.
What about adding a simple eventing screen? Not a working event system for this, buta screen that lets you input events just to have them down.
More explaining:
You manually input all events, so on another screen, there would be text boxes under titles like "input", "output", "output parameter", where you input the names of the events, then in the actual event screen, the event would show up as an option.
Another thing that would make it better would be that you would type "onactivate" into the input screen, then, after that text box, you would enter a list, "Self, Player, Client, Minigame, Namedbrick". This means that all these options are connected to "onactivate" and any other input event you add, such as "onplayertouch". After you enter the subject (Player, Client) the same is for the output, and that one output is connected to that one subject.
I'm tired and this probably isn't explained well.
