Add Message to Redwood Screen Using Visual Builder

Summary:

In the legacy Requisition Line page, we have added a pop-up message to the user to remind them to switch the default Source Org if necessary based on the Source Type as "Inventory" and Line type as "Goods". When we switch to Redwood, we are unable to add the same message and Visual Builder does not currently support messages in the page. Is there a way to add a pop-up message in Redwood similar to the one shown below either through Visual Builder or another process?
