[Paraview] Push/pull parameter?

[Maxwell, Thomas P. (GSFC-606.2)[SCIENCE APPLICATIONS INTL CORP]]

When configuring a parameter for a reader plugin in the server manager XML, it is possible to define a single SourceProxy parameter that does both data "push" and data "pull" to/from the reader?   If so, can you point to (or supply) an example?

Thanks,
Tom
