Line layouts, templates and clonning the line

It would have been nice to have line layouts such as;
-For buy levels set a colour, lets say green dotted line. Save the layout and next time when you need to draw a buy level simply just choose the layout.
-Also clonning the line would have been a great tool to have. For example click the line while press and hold ctrl clones the line and you can have the second exactly same line(colour,style, margin, note etc.)
 
Thanks for the support.
