Sharepoint Designer 2007 Workflows
In Sharepoint designer 2007, I am creating a workflow where I am trying to use 'collect data from a user' for multiple users.  In my document library, I have a list name field.  That list name field ties to a list which has between 1-15 users in the associated list.  I only need to collect data from user for those users in the list that are not null/empty.  I would also like to collect data from the users at the same time (parallel).  

It appears you can only use parallel within one workflow step.  Within one workflow step, it doesn't appear that you can set multiple conditions/actions.

What I need to do is this:

Condition 1:  If variable:reviewer1 is not empty
Action 1:     Collect Document Review from variable:reviewer1 (output to ...)
Condition 2:  If variable:reviewer2 is not empty
Action 2:     Collect Document Review from variable:reviewer2 (output to...)

Is there a way to do this that I'm missing?  

Thanks!
