Show only the 1 rep max for the selected body area on the online charts

When selecting charts then selecting more online information. It would be great if when you use the drop down to look at a specific area, I.e. back, biceps, triceps, that the bottom chart for the one rep max showed only the exercises for that area, instead of all the exercises. Possibly you can ad an area category named ‘all areas’ for those people to select for people that want the 1 rep max chart to show all of them at once.
