Check mark for type of Footprint selected

Once i have zoomed in to see the footprints, a menu on the left toolbar appears showing the different chart types - Volume, Trades, BigxAsk and Delta. Each of these have several chart sub-types. A user selects a certain type / sub-type to try which works best for the user but there is no way to know later which chart sub-type was selected. Could you kindly show a tiny tick mark or a “dot” against the selected footprint chart sub-type? Alternately, the name of the chart type at the lower toolbar perhaps.
