Is it not possible to make race-specific ArmorAddons for a race set to use DefaultRace armors?

[Mud]

I was going to attempt to make a compatibility patch for certain hats and accessories for the Elin race mod, as their unique head mesh makes most headgear sit in the wrong spots, such as the Wa Ribbon mod floating above the Elins' heads. But I found that when attempting to create ArmorAddon entries with edited meshes to be used only by the ElinRace and ElinRaceVampire races, the selections would deselect themselves upon clicking OK, and adding the new AAs to the Armor entries would make them stay hidden unless Show All was checked, a sign that the criteria needed to use that AA wasn't being met. Sure enough, wearing the items in-game just continues to use the mismatched positioning.

 

Google found me little more than other people lamenting the same problem, and some seemed to suggest that the only way to assign specific races to an ArmorAddon was to have the race not use DefaultRace as its armor assignment, which would cause the much greater problem of having all armors fail to show up on the race unless a patch was made. Is this the case? Are my efforts for naught, and the only way to have a race-specific appearance is to make an entirely new item entry using the edited mesh?
