Excel 2010: Formatting Multiple charts at once.

New here. I tried format painter, multiple select with CTRL (doesn't give me the chart tools option) or F4 for repeating formatting. I have multple scatter plots and need to make more. I'd like to be able to add a Trend line WITH the equation and R^2 to every chart at once. Also, with this I could toggle between linear and polynomial trend lines.

Thanks.

Anyone? anyone at all? no? Just so that I'm clear, I have multiple scatter plots and I want to know how to customize all of them at once, instead of going through each one individually and making the same changes over and over again.
