How to Mark join as left outer join in Info set

Hi Folks,

I have 2 info cubes in Info set, I need to mark the join as Left outer join.

I have read some blogs where is says that it cant be joined, but one of my colleagues has made left outer join using two cubes.

I want to replicate the same thing into my design.

If i normally connect one IO to another cubes same IO- its a normal join- its not written as left outer join. I want to see left outer join written on my link.

I tried global setting but no use.

Am I missing some setting,
