Are you developing your own LEDfixture as well as the controller?

In that case you have good possibilities to achieve what you want.

First of all, RDM is not topology aware. The controller have no (or at least very little) possibility to know the order of the connected devices on the daisy chain RS485 link.

I see two ways forward:
1. The user have to plug in one letter at a time letting the controller discover it and then set the adress of it and indicate that next letter could be connected (for instance by light the letter in a certain colour).

2. Make sure that the LED fixture do not expose the next device for DISC_UNIQUE_BRANCH messages until itself have been successfully discovered and muted.
