SharePoint List w/ Tasks

[kwilliams]

I have a SharePoint List that has a Nintex Form and also a Workflow that assigns tasks.  I want the user to be able to update the list form and complete the task without having to go to each list.  I'm not sure exactly what is the best way to do this, add the list items to the Task form and the set a Rule on submit to update the Task and the list form?

Since the On Submit rules are really just for field combination validations, your Workflow needs to respond to the user's data changes in the task form and probably use a Switch action to branch to the appropriate update for the selected list.
So in effect your central workflow list will apply the proxied values to the other lists.

Central Workflow meaning the workflow I've created to assign the tasks. And on the Task Form, can I have the list fields? I've set them up in pages, with the last page being the Task to complete.
