Add the "Trigger" type in use-cases constraints

[PA]

Dear EA developers,

Would it be possible to create a new type for the constraints of a use-case called “Trigger” to note the trigger of a given use-case ? For the moment, I use a pre-condition that I call Trigger but I am not really fond of it…  

Thanks,
PA

We use a constraint type of "Trigger" (Settings | General Types | Constraints). What I would like to see is a specific place in the Use Case for the trigger, and 2 columns in the scenarios: 1 for the actor, and 1 for the system, so that we could clearly document the dialogue.
