I have 11 Dv's included in a single canvas. Here once customer select a dashboard filter and scroll down across Dv's, its difficult to remember the selected value. Since the freeze option is not available now, they have to come all the way up to see what's the selected value. As like Excel, Filter selection should be frozen and should be available to cross verify below data. Also this way helps to change the filter value to a new value without scrolling up and down multiple time.
Find the screenshot. No way I can find the dashboard filter while checking the tabular details.
