overriding library subflow properties in an IBM ACE Application using ibmint

Question

Say I have an IBM ACE application with the following structure:

Application.V01
-- MessageFlow
----subflow1
-- MessageFlow2
----subflow1
----subflow2
-- Library
----subflow1
----subflow2
--------subflow1

Now, I am creating a bar file with overrides, using the command ibmint package --compile-maps-and-schemas --input-bar-file "input.bar" --overrides-file "overrides.properties" --output-bar-file output.bar

In order to override the values of the properties on the nodes in the subflow in the library in the application, I need to do something like the following, in my overrides file:

MessageFlow/Library/subflow1#MQ Input.connection=CCDT

This works fine if I've only got one message flow, and the subflows aren't nested; but (without promoting properties and doing it that way - I can't change the code now) how would I go about overriding something like MessageFlow2/subflow2/subflow1? Would it be MessageFlow/Library/subflow2/Library/subflow1/#MQ Input.connection=CCDT? Or something else?
