[rules-users] DSL to multiline DRL?

Is it possible to have a single line of DSL convert into multiple lines of DRL? I want to hide the implementation of my rules from the user. So, using my previous post as an example: rule "group 1" when $a : Trans( $groupValue : prodCat, $date : date ) not Trans( this != $a, prodCat == $groupValue, date < $date ) $b : LinkedList( size >= 1 ) from collect ( Trans( this != $a, prodCat == $groupValue, date > $date ) ) then //do something end should become something like: rule "group 1" when There are mutliple transactions with the same value for prodCat then //do something end Thanks, Tim
