Isochrones timing on IPad version

Hello everybody,
I have started using qtVlm on my iPad as well (tablet version).
Making the first routings, I have noticed that there is no possibility to change the isochrones timing: it is fixed at 60min < 24 hr and 120 min >24 hr.
Is there a possibility to change this setting?
Thank you very much for your support.
 

Hi, there is a security, you need to unckeck "Automatic settings" to get access to some settings.
Before changing that it is best to move the quality cursor fully on the right (best quality).

Perfect, it works!
Thank you.
