Assassin and Ascendant Forum Portraits

I guess here is the best place to ask this question, according to support.

Is there any reason the Shadow's Assassin and Scion's Ascendant Ascendancies aren't represented among the forum portrait selection, while every other Ascendancy is?

Assassin's honestly my favorite portrait in the game, and I'd love to be able to use it here, but it's just not an option. Any way to get that added? Same with Ascendant, really. Not that I use it or would use it, but it's not even an option, and I'm sure others would appreciate it.
