Is there a way to add the Loyal Housemaid to a Glamour Plate?

[Yandere-chan]

Hello~ Ellie really likes this outfit, but can't find a way to add it to a glamour plate. It neither lets her convert it directly or add it to the Armoire. > w <

If there isn't a way to add it, are they planning on making a way to add it? Danke
