If I understood you right, this is just a matter of you assigning a Generated filename character to another game character(Event, Player or follower). You can do this already. On the sample project, there is an example for doing this:
You just need to use the event id 2 (Open Generator) to create the Generated Characters Char1 and Char2. Then go to the event id 3 and you will be able to assign the same Generated character for two different game characters, in this example, Player and Event Id 2.
