with the latest Nov2020 Update (https://powerbi.microsoft.com/en-us/blog/paginated-report-november-2020-feature-summary/#comment-5144700663) the feature "Search in parameter dropdowns" was announced. But it's limited for searching with "begins with.." logic.

Would be great if search experience in parameter powerbi<>paginated report would be same. hard to explain to users that they can search in PBI within slicer-value-text and in paginated reports only with "begins with" logic... e.g.: if you have a parameter-list like "Customername (Country)" you are unable to search for all customers in a country without a second/cascading parameter :(
