[rules-users] Concatenating rule conditions

I have a rule that filters an ArrayList based on dynamic filtering conditions, for example this list can be a set of documents and the filter can be a user property which is required later for document filling (e.g. private name). This is fairly strait forward, where I can perform something of the sort: Rule "test filter" When $cm: ConditionMatrix(), $document: ArrayList() from collect ( Document (user.isPrivateName == $cm.isPrivateName) ) Then //do something End Now comes my question: I have a different rule that holds a different set of filter requirements that works on Document object. For example Rule "test filter 2" When $cm: ConditionMatrix(), $document: ArrayList() from collect ( Document (Payment.isLegal == $cm.isLegal) ) Then //do something End Is there any way to combine them both?
