Inventory/armory question for those on PTR

heya all. so i am just curious if anybody who has started playing on the PTR can talk about the armory and inventory please.

specifically, does having the armory sort of allow you to have more inventory space by putting items on the paper doll for any given armory slot? so instead of a sword being in the regular stash inventory it would be on the paper doll?

thanks for any info.
