I have struggled to show water pools because it requires a blue boundary line to be drawn first and then shading added according to open or sump. It's hard to get the two elements to match well enough and I often need to redraw the shading where it spillls across the blue bounday line and doesn't quite reach it. For long streamways (I just finished drawing up about 5km streamway from Meghalaya India). Can we please have a drawing option that combines both the bounday line and shading in one go for each, open water and sump? Thanks
