Hi Welton -
No. A Tableau Project has no capability to automatically filter workbooks inside it just because the workbooks in question are part of the project. You'll need to add filters to each individual workbook OR create a Data Source with the filter in place, publish it, and then use that Data Source for all the workbooks you want filtered a specific way.
"Edit Data Source Filter" from the Data Source....
