Feature request? More than one arrow between two blocks

[Stephen Leach]

Is there a way to show two distinct arrows for two blocks e.g. A -> B; A -> B; ? I have an artificial neural network where there can be multiple links between neurons that I would like to display. At the moment I am using graphviz to do this.

I also need this behaviour! It would be *really* useful to me.
