Optional parameter

[rivet]

is it possible to create a custom function that has an optional parameter?

[Kent Searight]

Could you give an example as to how you'd use an optional parameter?

[Zero Tolerence]

I think, Rivet, that the answer is no. You could create a workaround for this, by creating a paramater that filters out a certain value, and then send that value when you don't need it.
