Transfer relationship?

Hello,

I am still relatively new to Power BI, and I am creating just a "one off" visualization from a static excel spreadsheet that is very large and has multiple tabs/tables.  When I imported the spreadsheet into power BI, I had to clean up a lot of data and somehow in the process, "relationships" were formed where it appears that all the other tables are pointed towards one particular table, but that table isn't the "master" table.   I need all relationships pointed towards the "Master".  Is there a way to easily "swap out" the relationships between the incorrect table and the correct table?  You can think of the "master" table as the mother ship continaining all info and the incorrect table as one of the shuttles with 1 part of 320 some separate parts of info if that makes any sense.
