Please Help: How To Change Source of Existing Table

I’ve created a master doc which has a table with all source data.

I want to create duplicate docs and link them with the one source data table.

The problem is when I duplicate the doc - all the tables are running off a duplicate of the source table.

Is there a way to change the table source doc or do I have to create a bunch of new tables and format and filter them all over again every time?
