Changing Period for all shown Charts by changing the Period at one place rather changing the Period for each Chart

Hello Everyone

By using Free- or Multi-Chart-Mode i have 8 different charts visible.

When changing the period there is no possibility to change the period for all 8 charts by one click. I have to change the period for every chart once.

It would be nice if there is a posibility to change the period of multiple charts at once.

best regards
Ivan
