Set List Item Permission in SharePoint designer 2010 Workflow

A customer asked me to program a SharePoint designer action that enables to set permissions on an Item. In Moss 2007 this was definitively missing. But then after a little bit of googling (or should I say Binging?) I found out, that this action was now added in SharePoint designer 2010. 
So when I created a workflow I couldn’t find the Action in the list.

The solution was to add an impersonation step to the workflow, and see there; new Actions are available including the one to set Item Permissions

The impersonation step runs under the Author of the workflow and not the one who started the workflow
