I know there's a command for it, but I don't know it off hand. The workshop does have a mod, specifically the "Expanded Atheneum (Modless Multiplayer Friendly)" mod by HatsuneZaku, which also adds all posters (and a few other items) to the house building mode. So far, the mod has worked quite well for me.
