[rules-users] multiple .drl files

Hello all, I want to create a baseline rules file with Fusion that does some basic aggregating that I know I will need later.things like keep running averages over the last minute or so of several object values. Is it possible to then "inherit" or at least reference those aggregates I am keeping track of from another .drl file in some way.allowing me to always keep my basic aggregation functions in one rule file and then add additional rules/functions to my rule memory space later.or must any further rules that wish to reference those aggregate or statistics objects also be contained within the same .drl file? I understand I can have multiple .drl files, but I am wondering specifically about referencing objects and variables created in another rules file. Thanks, Chris
