Navigating through hierarchies in Saiku Analytics.

Hi, I just made a mondrian cube which I'm testing in Pentaho BI server using Saiku Analytics Plugin (which seems to be the nicest tool). In JPivot, I could open the parent hierarchy tab to uncover its children, but I haven't found anything similar in Saiku.

Is there a way to click, for example, the year "2014" to reveal every month? If there is, can I do the same in the graphic view?

Hope you understand my problem, I found it difficult to explain.

Best regards.
