Help adding market share line over bar chart

I've added a sample of the spreadsheet that I'm working on and where I am stuck.

Basically, if you see the lighter pink charts on the right "Sum of Benchmark" values, I either want these to be plotted as a single line over each name, or a transparent bar chart that corresponds behind each month of data. You will see that it sits next to the data and is not especially helpful.

I've attached a picture of what I want it to look like in a perfect world. I drew the lines over manually...any help would be greatly appreciated!

Hi Character_Zero,
