[rules-users] Free Form DRL through BRL in guided decision table

Does the workbench extended entry guided decision table support this kind of syntax: ServiceLineStatusInfo( claimStatusCodes contains "$param" ) Where $param is replaced with the value of the column? When I add that through New Column->Add a Condition BRL Fragment->Free Form DRL all I get is a checkbox column. Is there a way to set that up so that it allows entry and does the substitution? I know the line above could be built easily in other ways. It is just an example to illustrate. I have some more complex logical constructs that I'd like to do in straight DRL fragments if possible. Thanks, Joe
