2 different PPF actions triggering two different smartforms

Hi,

How to trigger two or three different smart-forms (which are triggered using different PPF actions) on to the same spool?

Suppose I have two ppf actions

1. triggers  X smartform.

2 triggers   Y smartform.

one after the other. Now the requirement is get the both into one spool. I know we can do by open-spool and close-spool. But I'm not looking for this solution.

Is there any specific configuraation with PPFs?

Thanks,

Sandhya
