Feature Request - Change data range for multiple series

I have a chart having 50 symbols all with the same data range, for example, 30 days back.

When I need to change the data range to 50 days, I have to repeat it for all 50 symbols which is a nightmare.

Is there any convenient way?

If not, please add this feature to one of the next releases.

I would call this as Range Linking.

We will consider it. Thank you.

One of natural place to allow modification of data range or other settings for multidata series is Format Objects dialog. It has Symbols tab which has
Data #, Symbol, Range, Last Date, Interval, SubChart #, and so on. People would like to change these fields anytime and conveniently.

Why don't you make these fields directly modifiable from the Format Objects grid?

OK we'll give it a thought.
