Have you explored the Go To Related Record script step?
This will allow you to view all the records in a portal on another layout.
I'm guessing the related table occurrence (TO) of your portal is based on a table called Time Billing Data. You can use this above script step to view the records of this portal on another layout that has the same underlying table.
Thst "other layout" should be based on the same table as that specified for the portal.
