Select trendline during backtest visualisation

[coolczus]

Hello,

In my expert advisor I have created a trendline that is selectable, but when I try to run this expert in the strategy teszter I cannot select or move this trendline...

It works fine in MT4. I mean in MT4 during the backtest I can select a trendline created by the expert and move to another position with my mouse. In MT5 I cannot.

I should enable this feature somewhere? 

Thanks in advance, 
Peter

PS: I use this trendline in MT4 to modify all of my stoplosses together.
