How to add a panel on Epicor's customized Screen?

I am trying to add a panel / banner to a customized screen on Epicor.
In my customized screen there are few tabs and I want to set this panel in a way that it should be able to displayed regardless of the tabs selection.
Panel is supposed display some data that pulled from the database based on the PO Number.

Is that possible?

I am attaching a pic for better clarification.
