I need to add a field to the AP Tran container. Do I need a connector license

For a custom report I am making, I need to add the posting date which is not present in the AP tran container. The fiscal period and year is present, but not the post date. I happen to want that. 

Do I need to make a new container to do this and if so, do I need connector license? I think the answer to both questions is Yes, but I want to confirm it. 

Thanks,
