Hi Matt—thanks for surfacing your desire for this functionality. Parting ways from the interactivity of a linked record field, lookup fields are computed and therefore will always take the form of an unclickable array, so it wouldn't be possible to achieve in the manner described. That being said, I did happen to discover this thread where users discuss this exact scenario; it might be worth checking this out for other ideas.
If you're super desperate for this functionality, perhaps you could try: 1. Creating one linked field per breakout field 2. Creating an automation that'll trigger when any of those breakout fields get updated 3. Making that automation paste the values from the breakout fields into their respective linked field
