"Nodes" on flow chart shapes

[Mark]

In Visio 2003 can I add connection "nodes" to flowchart shapes?

By "nodes", you mean connection points? Certainly, once the shape is placed.
Can't edit the master shapes on the master stencil though. But, you can
create a new stencil and copy these modified shapes to it. Save the new
stencil and these shapes will be available whenever you call up that stencil.
