A few ideas.
When adding / editing action plan tasks, we could change the "After Lead is Created" to a drop down allowing for either "After Lead is Created" or "After Lead is Assigned".
Another options would be to simply use a check box for the action plan forcing all tasks to use either the date created or date assigned.
Or of course.. We could switch it all together to just use the assigned timestamp.
Morgan.. Let me know what you want done. :-)
Cheers!
