Boolean logic with inlist in Lumira?

Hi All,

I was wondering how to do the following

If (field inlist ("A", "B", "C")) then 1 else 0

So far I can't find boolean inlist function in Lumira.

To accomplish the above I would have to do the following

1. Create new grouping field (ie: Group X = ("A","B","C")

2. Then do if ( groupfield = "X") then 1 else 0

Kind of cumbersome, but at the moment I don't know any other way.

Any suggestions would be appreciated.

Thanks!

David
