summary bar label

All,

I'm organizing the layout using activity code, all the activity names are using English, and at the right side of the bar, I'm showing the bar label use another language to translate the activity names, so the people didn't know English can read the schedule.

My Question is: are there any way to showing the same for the summary bar (the summary bar label only can show the description of the activity code, but i don't want the activity code description be bilingual)

Thanks for your reply.
