Query Timeout in Saiku - Where to change it?

Hi all. I am trying to find where I can change Saiku query timeout but I had no success.

Sometimes I have to press the "play" button two or three times in order to retrieve data from the cube but it wouldn't be necessary if I had 1-2 min. timeout instead of 30-secs.

Could someone help to find out how to change this property?

Thanks in advance!
