Drill down functionality on Hierarchies in Crystal Report for Enterprise

Hi

I am trying to add a drill down function at each node on any given hierarchy. However I am coming up with blanks everywhere I look. I know it's possible to do this on Crystal Reports 2011, but I am yet to find a solution on Crystal report for enterprise. The only solution I have found to delineate between the different nodes is to use the group indent feature in the groups and sorts section. However this indents the entire row, rendering the function virtually useless. Again I know in CR 2011 you could add code to counteract this indentation for the key figures, but I have been unable to determine if this is possible in CR for Enterprise.

Therefore my question is, can you add a drill down functionality to hierarchies in CRE and can you also add a group indent on the groupings in a way that does not indent the entire row.

Any help on this would be awesome as I am going in circles at the moment

Thanks

Neil
