Grouping parts of data in a column (ReportNet)

[Bjarkio]

Hi

I'm quite new to ReportNet but have a quite a sense of what I can (need to) do after using BO for quite some.
I have 2 questions:

1)
How do you group together part of data and leave other as they are?

For example data of one column is: ONE,TWO,THREE,FOUR,FIVE,SIX and I want to see it as "top 3", FOUR,FIVE,SIX.
In other words group parts and see other unchanged.


Thanks
