zero waited links remove the source

[Penberthy]

if your data has a zero waited link the source node is removed from the diagram so that if:
A => C with 5
A => B with 5
B => C with 0

B doesn't appear one the chart
A is size 10 with only half its value going to C

What i would like is for the elements to be positioned as if B => C had a value > 1 but with no visible link from B to C.
