Transformation equivalent to 'Blocking Step' in Pentaho

Hi Experts,

I just wanted to confirm if there's any function/transform in BODS which performs the same/equivalent functionality to 'Blocking Step' in Pentaho tool.

Here's what 'Blocking step' does :

The Blocking step blocks all output until the very last row is received from the previous step.

At that point, the last row is sent to the next step or the complete input is sent off to the next step. Use the Blocking Step for triggering plugins, stored procedures, Java scripts, ... or for synchronization purposes.

@Dirk Venken : How can we achieve this functionality?

Thanks in advance.
