Hi jeanfabre!
Thanks for the response, I'm sure it will be useful for other people looking for responses!
However, what I'm trying to achieve here is to store the "reference", in order to tell dynamically to a FSM witch list it should go through, without it being to heavy (not "find array list" every time the list must change, neither doing states duplicates for each possible lists).
If there was an action to store the list reference on the owner object, it would be really fast to set that up!
