This might sound too simple... but I really need a way to draw guidelines on my wireframes. So far i've been using "vertical & horizontal"line widgets to help me draw guidelines on my wireframes. and if i dont want to have them appearing on the prototype. I need to convert them to white lines or delete them before publishing.

Is there any other way of doing this?

Can we have something simple as what we have in any drawing packages (photoshop, illustrator and visio)? Just drag a line from the ruler and wala here is my guide.
