Hi  Nfuentes86 ,
Thanks for reaching out to the Microsoft fabric community forum.
Thanks, arvindsingh802 , for sharing such a helpful solution! I tested it in my workspace by replicating the steps, and it worked successfully. Appreciate the valuable insight!
Please use this Dax query to dynamically change the Title based on slicer slection

Title = CONCATENATEX(ALLSELECTED('superstore (1)'[Country]),[Country],"&")

For more information on Concatenatex: CONCATENATEX function (DAX) - DAX | Microsoft Learn

The dax query works for multi slicer selection as well
