add an optional parameter to InputMap.action_add_event to insert the event at a specific index.

I am making a rebind button and I want to have two separate bindings for each action. One for keyboard/mouse and one for controller. In order to make this work, I needed to write this function that would insert an action at a specific index in the event list for each action:

func rebind_action(action:String, event:InputEvent, insert_index:int=-1):
	var events:Array = InputMap.action_get_events(action)
	# remove all the events after this event
	var removed_events = []
	for i in range(posmod(insert_index, len(events))+1, len(events)):
		removed_events.append(events[i])
		InputMap.action_erase_event(action, events[i])
	# erase the old event
	InputMap.action_erase_event(action, events[insert_index])
	# add the new event
	InputMap.action_add_event(action, event)
	# add all the removed events back
	for e in removed_events:
		InputMap.action_add_event(action, e)

It seems like I shouldn't have to do this to get such basic functionality. Could a new parameter be added to InputMap.action_add_event to simply insert the event somewhere other than the end of the list?

Or am I not supposed to be using the array indexes this way?
