Have an RPC wait?

Options
In my scene I have some items that a player can pickup. When a new player joins those items are visible to them and the RPC to have them disabled happens before the item is created so I get a "PhotonView doesn't exist" error. Is there a way to have an RPC wait until the level is loaded before calling it, it looks like right now the RPC is called as soon as the player joins the lobby, but I want to have it load after PhotonNetwork.LoadLevel.

Cheers,
Ben
