Hi,
Why don't you use an activity for call list generation. When starting the call this activity is then directly used as interaction record for the calls and is marked as interaction record in the docflow. If you just want a different view, you can activate navigation to the activity details by help of 1424852 Interaction Record: Enable Navigation to Business Activity
Best Regards,
Sigrid
