I need to set the a SharePoint 2010 reusable workflow to "All at once (parallel)" by default in the initiation form. When a workflow is started manually, the initiation form displays for the user to fill out. However, I can't seem to find the setting to make it default to "All at once (parallel)".
I know it can be done, because another reusable workflow has it set this way. I used "copy and modify" to create this second workflow, but it didn't retain the "All at once (parallel)" selection.
