References DLC units without creating whole new mod

[ITcore]

Current mod changes upgrade lines and some combat strength for some vanilla units. I want to update it for Australia. It's probably like 1 or 2 lines of code. Is there anyway I can put in the code and have it alter the DLC unit only if the DLC is present without having to make a whole new mod?

Or do I have to make a whole new mod for it?

It looks like the .modinfo format has been updated with a "criteria" attribute. The Austrialia mod uses that, I suspect, to attach files conditionally:

  <ActionCriteria>
      <Criteria id="Australia">
          <LeaderPlayable>StandardPlayers::LEADER_JOHN_CURTIN</LeaderPlayable>
      </Criteria>
  </ActionCriteria>
  <InGameActions>
      <UpdateDatabase id="AustraliaGameplay" criteria="Australia">
          <!-- ... -->
      </UpdateDatabase>
  </InGameActions>

I suggest trying the same thing in your mod.
