Quick Tool Toolbar

     Hi, I have Adobe Acrobat XI 11.0.13. On the quick toolbar I would like to add some custom drawing markups. As of right now, I have one RED draw line and one RED draw arrow. How can I add another draw line and another draw arrow but with a different COLOR. Lets say a GREEN draw line and a GREEN draw arrow. So now I can have four items to my quick tool toolbar. And eventually I'll be wanting to add different color tools. But as for now, I only need one RED draw line, one GREEN draw line, one RED draw arrow and one RED draw arrow.

Thanks in advance
