CMD2 Persistent history InteractiveApp __init__ kwargs

[Puissant Clement]

I'd like to use the "persistent_history_file" feature from CMD2 but cliff InteractiveApp prevent me to do so without copy pasting the whole code of the class (unless i'm missing a cleaner way to inherit and edit that without running things twice ?)

Current code:
class InteractiveApp(cmd2.Cmd):
   def __init__(self, parent_app, command_manager, stdin, stdout):
      cmd2.Cmd.__init__(self, 'tab', stdin=stdin, stdout=stdout)

What i'd expect:
class InteractiveApp(cmd2.Cmd):
   def __init__(self, parent_app, command_manager, stdin, stdout, **kwargs):
      cmd2.Cmd.__init__(self, 'tab', stdin=stdin, stdout=stdout, **kwargs)

Thanks,

Clement

In order to access to this signature:

                 persistent_history_length: int=1000, startup_script: Optional[str]=None, use_ipython: bool=False,
                 transcript_files: Optional[List[str]]=None) -> None:
