Add "Size" default option for Scatter plot and Map chart

Can we have a "Size" default option to set for any newly added Scatter plot and Map chart? I think it's going to be very useful if we can set a default size of the Marker of the to scatter plot and Map chart so it's one less thing we have to set up when you add a new one (i.e. right-clicking on a Scatter plot/Map chart -> Properties -> (for map chart -> Layers -> select layer -> Settings ->) Size -> change the Marker size slider).

The Scatter plot/Map chart options can be found under Tools -> Options -> select Scatter  plot/Map chart or Tools -> Administration Manager -> Preferences -> select  desired group-> Scatter  plot/ Map chart-> ScatterPlotPreferences/MapChartPreferences.
