Before calling "attach" a screen object is just a dummy container for (row, col) values whose purpose is to be sent as part of the "attach" function call anyway. Just create the screen in an attached state directly. Keep the complete (row, col, options) config together. It is still completely valid to later detach and re-attach as needed, including to another session.
