Lashing up Legacy powered A, dummy B, Powered B, and Dummy A

With regards to Lionel ABA set 6-34513 along with optional powered B, 6-34514. These are early Legacy F7s with the R4LC chip (if pertinent). I know the units require individual (Engine) ID's for controlling unit specific features, but here is my question:

When assigning Train ID's, would I need to program ID's for every combination of units? For example train with powered A and dummy A, train powered A and powered B, train ABA, train ABBA, etc. Or, can I just make one ABBA train to cover any combination?

Not sure if the direction (on/off) of the headlights are part of the equation, but I think you have to address that option under Engines anyway. Sorry if my question hurts your brain, but neither the engine manuals or Legacy manual helped. I'm trying to conserve my limited lash up count.

Thanks...Rich
