It might take some finagling but we should be able to figure something out. However, it would be much easier with a packaged workbook so we can see what you've tried and have data to manipulate. If you have sensitive data, check out Anonymize your Tableau Package Data for Sharing.
I finally created a sheet for the headers of each report (one header that has 'main brand' and 'sub brand' another with Price in market 1, etc.) and hid the headers for the reports with the data. Like this if a user clicks on the sort buttons, nothing happens.
Not very elegant, but it did the trick for me.
Thanks a lot though!
