Change Table Visuals Columns without dragging new column in.

Is there something like query editor for Bi Visials?  I want to remove the "Old" part of the table name on multiple columns, so that the table visual looks at a new table called "Table: Absence Recording" that has identical columns.  

Obviously I could drag the new columns from the duplicate table into the table visual and then format all the columns, but was wondering if there was something like a background editor that I could simply remove "Old" from all table column names, keeping all formatting, etc.

Hope that makes sence.
