There is - the initial_stdin argument can be passed to the slave side
"shell" command.  The master-side steps.ShellCommand does not have
explicit support for this feature, though, so you'll need to write a
custom step.  See the developer docs for a guide to doing so.

You could also consider doing it with a shell redirect.
