Combing two activity totals? (Read 362 times)

This may be a stupid question with an obvious answer, but here goes:

I have various groups of two activities I wish to combine for a complete distance/time total. For example, Mountain biking and road riding. At present I can put them into my graphs and data as seperate activities, which is great, however when viewing distance summaries, I can only select one at a time.

What I would like to do is have mountain biking and road riding as seperate activities, but be able to combine the two to be one total summary of "bike", so I can get an idea easily of my total miles/time.

I know I could create one activity called 'bike' and create different workout types, but then these different colors do not show up in my activity duration graph unless I create another graph specifically for that activity. Is there a way of displaying, in the activity graph, different workout types?

I guess all it is is a way of combining the data of two or more activities into one 'summary'. Is this possible?

Thanks eric, I figured once tags is implemented that will be able to help, ie displaying combined data of a certain tag applied to different activites.
