Hello,
I have created a quick step in SharePoint Designer 2010 and want to customize the workflow form so that I can add user/group picket field, choice type filed, but there is not such an option in that kind of form. Instead I noticed that as a type can be chosen XML document, which , I suggest should allow to add custom field types. Do you have a sample of that kind of XMl?
The problem is that before starting the workflow I want the form to make some filters depended on a date to show users that are in other list with the same date in an item.
