Unfortunately, there is no option to share the "saved filter" since its specific to the user who wants to filter the dashboard as per their need.
You can contact Qualtrics support to file a feature request for this.
Creating a role and then providing access rights to role rather than individuals is not going to work for us, it is too much maintenance and we have too many directors that want to share filter lists with managers. We would like the ability to share filters to be part of the product.
