Matt, 

It's simple, but not as simple as a flag.

You need to add the annualized metrics to the portfolio specification
with a multiplier of 0.

Then you can plot your efficient frontier using all the standard
PortfolioAnalytics tools calling those metrics as axes of your plots.

Let me know if you need a fully worked out example, but I think there
are examples in some of the vignettes and presentations that do
something similar with annualized standard deviation.
